Do you have an amount in box 14 for state withholding? If not leave boxes 14-16 Blank. Or put in the same amount as box 1.
Yes, I do have withholdings. I checked previous ones, always had withholdings in 14 but nothing in 16.
If there's State Withholdings in Box 14, there needs to be an entry in Box 15 (State ID) and Box 16 (State Distribution Amount), or there will be an error.
