Check with your parents. They sent out the first Stimulus checks based on either your 2018 or 2019 return. Did you file a 2018 or 2019 return? Did you check the box that you were a dependent? Did they claim you in 2018?
If you can't be claimed on their 2020 return,
The Stimulus Check is really based on 2020 tax return. Any amount you already got will be reconciled on your 2020 return line 30. If you didn't get a Stimulus Check (and qualify) or you qualify for more it will be added to your 2020 return. But the good news is if they paid you too much they won't take it back.
When you go through the federal review tab it will ask how much you got if any. Or to enter your stimulus payment in TurboTax, type "stimulus" (without the quotes) in the Search box, then click the link that says "Jump to stimulus."
