You can reconcile your stimulus money on your return. On your 2020 return (filed in 2021), you will be asked about the stimulus money. Enter any amount you have already received (if any) . Then the program will calculate if you are owed more money (which would include any amount you qualify for the second stimulus money), or it will show you don't qualify.
After the Other Tax Situations section (Federal Review) of the 2020 TurboTax program you will be asked about the stimulus payment received or not received.
After you asked about the stimulus payment & you qualify, you will get the Recovery Rebate Credit (stimulus) on the 2020 federal tax return, Form 1040 Line 30.
