So I think everything starts as an opinion, because anything that's informal and not necessarily fact. However, some statements must rise to the level of objectivity for something to be considered objective.
So, what makes opinions become objective?

I would say that one way for opinions to become objective is to pass the empirical test. You can test your opinions and find out if they are right or wrong. If an opinion becomes objective, it will not be an opinion anymore, rather it will become a fact. It is not a personal opinion that the speed of light has the value that it has and it is invariant in every inertial reference frame.
Would it be useful - perhaps not - to treat 'objective' as a contrast term ? To say that an opinion is objective is to claim or to presuppose that it is not biased, not idiosyncratic, not prejudiced, not the outcome of self-deception ...? In this case there would be no feature common and distinctive to objective opinions, simply a number of features any one or mix of which could deprive an opinion of objectivity. One implication of this approach is that there is no necessary connection between objectivity and truth. My opinion about X might be free from bias, idiosyncrasy, prejudice or self-deception but still be false. (Unless, of course, the list left open and incomplete ('...') contains features which do rule out error. It isn't immediately clear to me what such features might be.)
Let's first define "objective". "Objective" means that a statement is not dependent on the subject that made it to be true.
"objective /əbˈdʒɛktɪv/ (of a person or their judgement) not influenced by personal feelings or opinions in considering and representing facts." https://www.lexico.com/en/definition/objective (Oxford Dictionary)
Let's define "opinion". A jugemental view someone holds that has been concluded from subjective information (like feelings or thoughts) or objective information (like measurements or observations).
"opinion /əˈpɪnjən/ a view or judgement formed about something, not necessarily based on fact or knowledge." https://www.lexico.com/en/definition/opinion (Oxford Dictionary)
"This icecream is tasty, in my opinion." is a jugemental statement based on the things you felt. Thus it is inherently subjective. Making it by definition a subjective opinion. It may not be proven wrong due to its subjectivity.
"Pluto is a planet, in my opinion." is a jugemental statement based on measureable information. From the measurements, there are words to define what qualifies as a "planet". This is called the "objective criteria" and it may be satisfied to reach the conclusion. The fact that the statement is seperate from the subject makes it an objective opinion. Of course the question if it is true can be discussed (the truth of the statement is of no concern in this instance). Therefore it is not an universally agreed fact but instead a judgemental view - an opinion. To say "in my opinion" is redundant here and not often used when talking about objective opinions. That does not not make them opinions.
Neither opinion nor objectivity are particularly tightly defined hence any statement as to the point at which they change state is, by necessity, opinion (somewhat ironically).
However, what I like to use as a yardstick for objectivity is if it is feasible for others to come to the same opinion and, by applying reasonable rules of evidence and logic, they will come to the same opinion.
Using this approach, MarkOxford's "I find tomato's tasty" could never be objective but "tomatoes grow on tomato plants" can be.
You may note that what I've really done is replace the, somewhat vague, terms of opinion and objectivity with the, also vague, terms of feasible and reasonable. I don't believe there's a better approach but that, of course, is just my objective fact.
Subjective facts are allowed to contradict each other and still be considered correct. Consider:
John: Durians are disgusting!
Amir: Durians are delicious!
Each person believes their own statement to be true. Each person accepts the other person's statement as valid from the other person's perspective. They might consider the other person to have strange tastes, but they don't think the other person is lying, ignorant, or misinformed.
Objective facts are not allowed to contradict each other. Consider:
John: Durians are a type of fish.
Amir: Durians are a type of fruit.
A reasonable man would say that at least one of these statements is false.
If enough people share a common subjective view, then society as a whole acts as if it is true, and the reasonable man would say that it is true, and anyone disagreeing with it is clearly wrong. The fact then becomes objective. (It might very well be untrue, but that would be irrelevant.)
