I have a W2 that shows the State employee ID as "TN NOT NEEDED". The state is blank, wages are entered. TN does not have state taxes, & is not selectable. how to Enter?

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
