Any Particular tax form? And which state?
I know that for NC, for withholding on a W-2, there is a checkbox tha must be hit on one of the follow-up pages.
And for a 1099-R, for NY (and perhaps a few other states), box 16 of the 1099-R must be filled in with the distribution amount, even though it's empty on most 1099-R forms.
