After you file

If you don't receive your stimulus payment  by the time you file your taxes, you can make an adjustment on your 2020 tax return for stimulus payments you qualify for, but have not received. 

To do this in TurboTax, please follow these steps:

1. Enter the information in your return.
2. Click Federal Review at the top of your screen. 
3. On the screen, Let's make sure you got the right stimulus amount, click Continue.
4. You will be asked about the amounts of first round and second round stimulus payments you received. 
5. TurboTax will then calculate the amount of stimulus payment remaining that you are still entitled to.  This will show as a credit on line 30 of the 1040.
