A reduction in your refund for the recovery rebate credit is most often caused by user error---when you were asked how much you received for the third stimulus check -- the one for $1400 per person sent out from March to May last year----did you enter the total amount correctly? Did you use the amount from BOTH spouse's letters 6475? Or did you say you did not receive the full amount and thereby put an amount on line 30 of your Form 1040? If you received the full amount already then your line 30 should have been blank. There should only be an amount on line 30 if you did NOT receive all of the 3rd stimulus.

Does the IRS show that you received a $1400 per person stimulus or EIP check in 2021? Did you receive it? When you were asked on your tax return did you say no? Was there $1400 per person on line 30 of your tax return?
If the IRS says you got $1400 last year but you did not receive it you can have it traced.
