You may be considered to have supported yourself during the year, but it's not possible to say without knowing the particulars of your situation, especially since you lived with your parents. You'll need to sit down and run the numbers yourself to make a determination.
You should compare how much you spent on your necessities, including education expenses, during the year, with how much your parents spent.
Please see the TurboTax Help article What does "financially support another person" mean? for guidance.
