Ok the difference the IRS sent out was 2800 (3612-812). The rest was probably the Turbo Tax fees plus the Extra $40 Refund Processing Service charge (45 in California).
The 2800 is the 3rd Stimulus payment.
1,400 or 2,800 (or multiples) is the 3rd Stimulus payment. Did you already get the Stimulus payment they sent out last year starting March 2021? The IRS has records that show you were sent the 3rd stimulus payment so they removed the $1,400/2,800 Recovery Rebate Credit.
Do you have an amount on 1040 line 30? You might have tried to claim it again. Line 30 is only if you didn't get the full amount or qualify for more.
Double check your bank statements and check your IRS account to see what they sent you. Check both IRS accounts if married.
