did the employer include box 11 in box 1?
w-2 box 11 instructions
Box 11. This amount is (a) reported in box 1 if it is a distribution made to
you from a nonqualified deferred compensation or nongovernmental
section 457(b) plan, or (b) included in box 3 and/or box 5 if it is a prior
year deferral under a nonqualified or section 457(b) plan that became
taxable for social security and Medicare taxes this year because there is
no longer a substantial risk of forfeiture of your right to the deferred
amount. This box shouldn’t be used if you had a deferral and a
distribution in the same calendar year.
