When I attempt to check Box 62c on Schedule 4, and increase the amount of additional tax, the form will not allow manual entry. Additionally, when I click "Edit" on TT, While is shows an "override" option, that option is not active.
Have you tried to enter the code and then the amount?
Box 12 codes are:
A -- Uncollected Social Security or RRTA tax on tips
B -- Uncollected Medicare tax on tips
M -- Uncollected Social Security or RRTA tax on taxable cost of group-term life insurance over $50,000 (former employees only)
N -- Uncollected Medicare tax on taxable cost of group-term life insurance over $50,000 (former employees only)
Thanks for the input. The W2 Box 12 Code is "Z". Schedule 4 will not permit me to either check or insert "Z" in Box 62c, and will not permit me to enter an additional amount on Line 62.
Thank you and this is what I found and posted in answer below.
