Interest on US Savings Bonds

I answered all the questions correctly and entered the interest in Box 3 from 1099-INT.  I did not say the interest is not taxable.  I did not use the interest to pay for higher education.  But TT deducted the amount from my state income.  I deleted the entries and re-entered.  It did not make a difference.  Why would TT deduct interest on US Savings Bonds when I did not say that the interest is not taxable?
