State tax filing

The Indiana notice you received should have a way to contact them to discuss this issue.   

The Indiana nonresident return should have 0 income entered since you did not live or work in Indiana.

 

The Indiana Schedule A Column B should have 0 entered.  That amount flows to IT-40PNR Line 1.

Look at the Schedule A and IT-40PNR that was filed to verify that 0 income was reported.
