If you're referring to box D on a W-2, are you entering the W-2 manually or are you trying to import it? If you are entering a W-2 manually, box D is not required. Just leave it empty. If you are trying to import the W-2, skip the import and enter the W-2 manually. It only takes a couple of minutes. It will be a lot faster and easier than trying to figure out why the import is not working.
It appears that employers sometimes tell TurboTax to require box D for importing the W-2, even though the employer did not put anything in box D.
