What state are you in? And......are you asking about a W-2? If you are asking about a W-2, is there an amount in box 17?
Several states do not have a state income tax. So these states will not show up in certain drop down lists. Leave boxes 15, 16, and 17 blank when you enter a W-2 for these states.
Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington and Wyoming
