Turbotax does not do form 843 and thus offers no help other than pointing out the over-withholding
how much over/is it worth it?
don't know if the online TM is the same employer as the one that you worked for and issued your w-2.
strongly doubt it from reading this:
"Off-price home décor retailer Tuesday Morning has been acquired by Hilco Merchant Resources for $32M in a court-approved bankruptcy sale—over the objection of a global management firm that argued it was prepared to finance Tuesday Morning's continued operations.
Judge Edward Morris of the Fort Worth division of the US Bankruptcy Court for the Northern Division of Texas overruled an objection from Invictus Global Management, which said in a filing it had committed $51.5M to support Dallas-based Tuesday Morning during its bankruptcy, RetailDive reported."
however, because of IRS requirements as to a statement to support the refund you should see if you can contact the business to make sure. after all your signature is under penalties of perjury.
If you cannot obtain a statement from the employer, you
should attach a statement with the same information to the best
of your knowledge and belief and include in the statement an
explanation of why you could not obtain a statement from the
employer. Attach a copy of your Form W-2 to prove the amount
of social security, Medicare, or RRTA tax withheld.
the maximum social security wage base for 2023 was $ 160,200 with the social security tax rate at 6.2% the max that would have been taken out is 9932.40
there is no maximum wage base for Medicare. the rate is 1.45%
if you filed an extension for 2023 you have until 10/15/2027 to file the 843
