If no amount was withheld in Box 17, you should leave Boxes 15, 16, and 17 blank on your W-2 form - this should clear the error and allow you to move forward.
Box 15: This box is for the state and employer's state ID number. If your state doesn't have an income tax (like Tennessee), you can leave this box blank
Box 16: This box shows the amount of your wages subject to state income tax. Again, if your state doesn't have an income tax, this box should be left blank
Box 17: This box shows the amount of state income tax withheld from your pay. If no state income tax was withheld, this box should also be left blank
