Get your taxes done using TurboTax

If you were listed on a 1095A form with your parents then you MUST get that 1095A form from them and enter your info on that form on your return.  Then ask your parents how much of the Premium tax credit they took on their return.   If they used 100% then you will take 0% on your return.  If they took 60% then you take 40% and so forth.  Follow the interview screens carefully ... read everything.
