I amended 2019 tax return and said I could not be claimed as a dependent on another's return. I did not receive a stimulus check.

Your 2019 amended return may not be processed yet by the IRS, and this may be the reason why you did not receive the stimulus checks.

If you are not a dependent in 2020, you should e-file your 2020 tax return and receive the stimulus payments as the Recovery rebate credit.

In TurboTax Online, to claim the Recovery Rebate credit please do the following:

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.
