How do I change the amount entered for economic impact payment? I made an error in the amount entered and cannot figure out how to go back and change it. Thanks!

To change the amount reported, you have to go through Federal review again by following these steps:

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 Did you [or your spouse] get a third stimulus payment?, answer Yes or No
4. Follow the interview and answer all questions
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.
