My husband and I filed our 2021 taxes jointly - he is self employed, I am not. Last year I switched jobs so received two W2's and paid a total of $13,329 in social security for just my W2's. Turbotax flagged this as an overpayment of $4,476 and credited it back on our return on Line 11 of Schedule 3. I just received a letter from the IRS stating there was an error in my return: "We changed the amount claimed as excess social security tax withheld or tier 1 RRTSA withheld on your tax return because you incorrectly calculated the excess amount". and I now owe that money plus penalties. Is the IRS correct? I thought the maximum payment for social security tax for 2021 was $8,853.60 so it seems I did overpay? May be possibly since my husband is self employed, but then why did Turbotax not catch this? Any help is appreciated!
