Deductions & credits

Medical insurance premiums that are paid with after tax dollars can be subtracted from income in Wisconsin. The amount subtracted does not need to exceed 7.5% of income.  I entered my premium payments in the federal section of  Tubotax (about 10K) but it does not calculate the subtraction when I do my Wisconsin state taxes.  This seems to be a flaw in turbotax.  What should I do?
