I have several W-2Gs from gambling winnings. None of them provide the name of the locality (box 18) yet TurboTax is saying that it is required. What should I do?

Leave Box 16, 17 and 18 completely blank. No spaces or any entry. If you have anything in box 16 or 17, box 18 will be required. I assume  you have a 0 in either box 16 or 17 currently.

Thanks, yes I have 0 in those boxes.  I will remove and see if that fixes the issue.  I appreciate your assistance!
