I need to know if our Indiana State Taxes that we owed got paid with our federal refund for 2015, 2016, & 2017

You can't pay your state taxes from your federal refund. That's because the IRS and state tax departments each maintain their own, separate tax collection systems.

The following link will take you to the Indiana.gov website where you can pay any Indiana State taxes that you owe: http://www.in.gov/dor/4340.htm
