After you file

@mjm77 The TurboTax program showed you the amount of the 3rd stimulus you were eligible to receive based on your Adjusted Gross Income.   You were asked if this was the amount that you received and how much you received from the IRS.  You entered 0.

Since you told the program that you did not receive a 3rd stimulus payment from the IRS, the program entered the Recovery Rebate Credit on the Form 1040 Line 30 based on the amount you were eligible to receive.

 

The IRS has records that show you were sent the 3rd stimulus payment so they removed the Recovery Rebate Credit that was entered on Form 1040 Line 30.

 

Go to this IRS website for your tax account to see if the 3rd stimulus payment is entered - https://www.irs.gov/payments/your-online-account
If you are Married Filing Jointly also check your spouse's tax account.

 

If you checked your bank account in the March - May 2021 timeframe and there is not a EIP3 payment from the IRS then go to this IRS website for how to start a trace on the payment - https://www.irs.gov/newsroom/questions-and-answers-about-the-third-economic-impact-payment-topic-j-p...
