Can someone please help me with the non-filer or 1040-1040SR?

Do you want to file a 2020 tax return to claim the stimulus payments as the Recovery Rebate credit?

Even if you did not have any income in 2020, you can use the free edition of TurboTax Online to prepare and e-file your tax return in order to claim the stimulus payments known as the Recovery Rebate credit. The federal return will file as usual and will not be rejected. Any state return should be removed, as there will not be a state filing requirement.

1. Sign into your account and continue from where you left off
2. Click on Federal in the left-hand column, then on Federal Review on the top of the screen
3. On the next page titled Let's make sure you got the right stimulus amount, click on Continue
4. Follow the interview
5. TurboTax will determine whether you are entitled to any additional stimulus
6. Any stimulus amount remaining due to you will show as a credit on line 30 of your form 1040.
