Thanks for your question.
I am not understanding. My form 1040, line 61 is the total of lines 56 through 60, and it has no designation for codes such as UT.
You must mean the dotted line next to line 61 where the initials may be added for a particular tax. "UT" would be the code for uncollected taxes, particulary:
uncollected social security and medicare taxes on tips, group life insurance or RRTA tax.
this should be reflected in box 12, codes A, B, M, or N on form W-2.
