For the workaround to use box 3 value in box 1 with "Nontaxable medicaid payments", there may be a round up issue. For example, if box 3 value is 1000.88, TT would somehow round it to 1001 somewhere, and Smart check would report an error say that the number can not be larger than 1000.88. I could round it down to 1000 to get around that, but it's still no ideal. No, even if I put 1000.88 during Smart Check fixup, it would still be rounded to 1001 and the error would come up again.
I really hope TT can handle zero box 1 value with excess social security tax withheld so I don't have to use any workaround every year.
