tyou answer correctly if they could claim you. the fact that they didn't is irrelevant.
1) did you live with either or both of them for more than 1/2 the year?
2) as of 12/31/2019 are you under 19 or under 24 if a full time student?
3)did either or both parents provide over 1/2 your support?
4) are you married and if you are did you file a tax rturn becuase you had a tax liability
if the answer to the first 3 are yes and the 4th is no, they can claim you.
if the answer to any of the first 3 is no or the 4th is yes. you can claim yourself but would have to amend if you already filed.
