The stimulus check is an advance on a credit you can receive on your 2020 tax return.  If something went wrong or you did not get the stimulus check this year, you can get it when you file your 2020 return in early 2021—if you are eligible.It will end up on line 30 of your 2020 Form 1040.

If you are not a dependent on the 2020 federal tax return and are otherwise eligible you will receive the Recovery Rebate Credit on your Form 1040 Line 30.

TurboTax will ask about the stimulus payment received or not received in 2020 after the Other Tax Situations section is completed.
