Why do you have two lines (W-2, boxes 15-20) for the same locality? Are you sure it's the same locality. Two lines, on an Ohio W-2 usually means you had withholding for both a School District (SD) and a City. They could have similar names.
Just leaving off the dash, when you type in the number, usually works. The instructions at the W-2 screen say to not include any dashes. TT automatically picks up the state ID number. There is not a separate ID number for cities or SDs.
