If you were a student for any one semester that started in tax year 2020, it is highly unlikely you provided more than half of your own support, meaning that your parents qualified to claim you as a dependent on their own tax return. Having lived with your parents that year and with only $14K of income, I seriously doubt you came anywhere close to providing more than half of your own support. It's possible that your tuition alone exceeded $14K for the tax year.
If you go back and change that now, you risk the possibility of both you and your parents being audited. Especially if your parent's claimed you as a dependent on their 2020 tax return.
