What's my 2024 AGI if someone claimed me as a dependent?

It all depends on whether or not you filed a return for yourself in 2024 .

If you didn't file your own return last year and you’re in TurboTax, just tell us you didn’t file last year when we ask you. But if you already entered a number, be sure to change it to 0.

Otherwise, if you did file your own return in 2024 but someone claimed you as a dependent (this often happens with college-age students), use the AGI from your 2024 return, not theirs.
