@michael_crist - the Recovery Rebate credit is totally automated by TT, with one critical exception.
at one point in the interview process, you are asked how much did you receive for the 3rd stimulus (paid by the IRS to you March - May. 2021). If what you entered does not match the IRS records, two things occur
1) Line 30 is inflated - in your case by $2772
2) the IRS will check all Line 30 entries and match the calculation against their records, and if they do not match, they will reduce Line 30 to match their records which has the knock on effect of adjusting your refund / increasing what you owe.
What did you enter when prompted by TT as the amount you previosuly received for the 3rd stimulus? (please check your bank records or Letter 6475 - please do not go from memory).
Also, I suspect you filed joint. If you entered what was stated on Letter 6475, there were actually TWO Letters, one addressed to you and one to your spouse. You had to enter the SUM OF BOTH letters when prompted by TT - this appears by far the #1 mistake I see via complaints on these boards.
does that help?
