I have W2s from two separate employers (different EINS). One W2 shows max social security wages and withholding. The other W2 shows non-cash compensation (cost of group life insurance) and shows amounts for both Social Security Wages and for tax on that amount in the Box 12 Code M (uncollected social security tax on cost of group life insurance). If I just put everything in TT, it carries the amount in Box 12 Code M to Schedule 2 Line 13 as an addition to my total liability. TT does not then produce a credit for excess withholding on Schedule 3 Line 11. I would appreciate any help. It seems like TT should treat the Box 12 Code M amounts as social security withholding and give me a credit for excess withholding on Schedule 3 Line 11.
