@ajanello - suggest going back and re-read the wording of the questions in the turbo tax interview section.
When everyone talks about the 1st two stimulus payments (EIP#1 and EIP#2), that refers to the payments received in the summer of 2020 and January of 2021 - those were reconciled on the 2020 tax return.
the 3rd stimulus payment (EIP3) refers to the payment received in March - May, 2021. You state you received that one but that is not what you told turbo tax during the review process.
So when TT asked in the interview did you receive that payment, you appear to have answered "no", when the correct answer was "yes". there were warnings and statements on the page if what you entered didn't match the IRS records.
Answering "no" placed $2800 on Line 30, increasing your refund. But the IRS knows what they sent you, so they corrected your return. No amendment necessary
Unfortunately, there is no error on TT's part (and I am not employed by TT) - go back and read the instructions that TT clearly stated in the federal review section..... this is not only a TT problem - millions of people, using other packages and doing it themselves did the same thing. if you did not enter what you had already received, the result was wrong.
the turbo tax guarentee is that their software calcuations are correct, but if the input is incorrect (which is the case here), then their guarentee doesn't cover that situation. Sorry about this, but if any consolation, you are in the same boat, as many, many others.
