Not a question just an FYI, your system made a $600 error on my 2020 tax return calculation

Probably not a TT error.  Sounds like you claimed the Recovery Rebate Credit, but the IRS records show you were already sent that $600 stimulus payment. (Unfortunately, some folks received debit cards for it, and threw them out because they though it was junk mail). The IRS will be mailing you a letter.

Or did the IRS send you $600 more? You might have qualified for more stimulus. Check 1040 line30.
