Federal Home Loan Bank interest deduction in Minnesota

My 1099's from brokers do not break out interest on these bonds from regular interest or include the amount with US treasury interest, so Turbotax transfers the wrong amount to my MN return.  How do I add in this interest in the exempt line so not taxable in MN?  Thinking of just using the override on form M1M to increase the amount, but maybe there is a better way?
