Investors & landlords

Thanks for your reply.  I don't think I made my question very clear.  I am in act l1ble for the taxes and enter the amount of social security and medicare tax due in TT.  While he fields are blank, I know what the tax due amounts are:code C $$$ x .062  for code M and code C $$$ x .0145 for code N.  So, I can calculate taxes due and populate TT to submit a return.  I'm just curious if this would create an issue with the IRS if the W2 they have received has these boxes blank.

ON another note, I retired from AT&T so Alight Solutions has distributed many thousands of these incorrect W2s.  I just wonder if the IRS software is "smart" enough to pick up on the fact that a code C amount should also have a code M and N amount.
