I have also received this letter for tax year 2021. I had two employers and exceeded the social security wages threshold in total, and had $11k withheld total ($2321 over the $8853 max). I see the difference is shown appropriately on line 11 of schedule 3, but I have received a letter from the IRS stating that I inappropriately took too much as excess social security. This math seems fairly cut and dried but I can't reach anyone at the IRS and I don't have enough visibility into TurboTax anymore to see where it may have gone wrong. Can I somehow view the W2's that imported after I filed to check for import errors? Or is this possibly a TurboTax calculation problem?
