How to I file for the 1040? I never received my stimulus for 2021

[MinhT1]

If you did not receive your first and/or second stimulus payment or if the amount received is not correct, you can claim it on your 2020 tax return 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.

I did not receive $ 600 second stimulus

If you are qualified based on the requirements and your 2020 Adjusted Gross Income (AGI), and did not get the second stimulus payment, then please ensure you are entering the amount of stimulus payments you did receive to ensure that the Recovery Rebate Credit calculates correctly.

Please follow the steps below:

1. With your return open, search for stimulus with the magnifying glass tool on the top of the page.
2. Select the Jump to Stimulus in the search results to directly go to correct TurboTax page.
3. You will come to a page titled Let's double-check the amount you received and it will list the first-round and second-round payments based on your 2020 return.
4. Answer No for the question, Is this what you received? 
5. Enter the amounts of the first and second round stimulus payments you received. In your case, you would enter $0 for the second stimulus received. 

Your Recovery Rebate Credit will be the difference between what you were qualified for on your 2020 tax return less the amount of your first and second stimulus payments you have already received.
