2 sets of boxes 18, 19, 20 for the same locality
On my W-2, I have 2 sets of boxes 18, 19, 20. Both 20 boxes state the same locality, so I get an error message when I try to enter them on separate lines. I saw other posts that suggested combining the amounts.
The amounts in the two boxes labeled 18 are different. One of them matches the income listed in box 1 and the other matches the income listed in box 5. So, combining them would not be accurate - it would nearly double my earned income. Which should I choose to list in box 18?
The amounts listed in the two boxes labeled 19 also do not match. Per my paycheck, both amounts were withheld - I'm guessing one is city and one is school district. Should I just add those together? Thanks for any assistance.
