How can I get the interest on US Treasury Bonds not to be taxable to the state of Indiana,? the first state that comes up on the drop down menu is Maine?

I am trying to add interest from US Savings Bonds on the federal income section.  When it asks which state will not tax this income, the first state that comes up is Maine.  I am trying to use Indiana.  When I get to the Indiana section it show that the interest is US Savings bonds but it will not let me update it and the interest is being taxed  How do I get around this?
