I can not find Tennessee on the list of states for box 15. What should I do?

Tennessee is not in the list for W-2 box 15 because there is no state income tax on wages in Tennessee. Box 17 should be blank or zero. If so, leave boxes 15 through 20 all blank. It is not necessary to enter TN in box 15, even if it's on the W-2 that you got from your employer.
