If TurboTax is telling you that there’s excess Social Security withholding of $186.00, that means the program is “seeing” Social Security withholding of $8,723.40 for your husband – the maximum amount that can be withheld ($8,537.40) plus $186. See Line 10, Excess Social Security and Tier 1 RRTA Tax Withheld in the Instructions for Forms 1040 and 1040-SR for more information.
SteamTrain’s guess that perhaps one of your W-2s was entered under your husband’s SSN seems the likely culprit. Double-check all of the W-2s that you’ve entered into TurboTax.
You might also try deleting all of the W-2s, then re-input them. Please see the TurboTax Help article How do I delete a W-2? for guidance.
Also see the TurboTax Help article Can I get a refund for excess Social Security tax withheld? for more information.
