Enter the Box 14 description/code from your Form W-2 in the first field in the row for Box 14 (e.g. TFB). A screen or two later, the program will have a drop-down menu to select a specific description/code; you won't see "Taxable Fringe Benefit", select "Other - not on above list".
If the Form W-2 does not have a Box 14 description/code, leave the
first field in the row
for Box 14
blank.
