Box 16 nothing is entered for Illinois (live here but work in Missouri).Box 17 has Illinois State Income tax withheld ($1394.81).Cannot file if withholding >20% of wages.

in box 16 of w-2 try entering the same wages as box 1.  However, the real problem is that box 16 should have your Illinois wages. ask your employer for a corrected w-2.   your illinois return is due by midnight CST.  Illinois may reject the return if the employer's filing with the sate also left box 16 blank. your wages should be in the $28,000 range for that amount of withholding.

thank you for your reply.  I did not work in Illinois, so I do not have any wages to enter.  All wages came from Missouri.  Not for sure why my employer took taxes out for Illinois? unless they were required to as I live here in Illinois and work in Missouri.
