I rented my home for half the year. Turbotax divided my repairs and maintenance in half improperly. It should only divide eg taxes and insurance in half, correct?

This was my first year renting my home, and it started exactly mid-year. So when I enter the amounts, Turbotax correctly divides the insurance, taxes, interest in half--this makes sense. But it is -also- dividing the repairs, maintenance, and supplies I purchased during the rental in half. This is improper--those are entirely related to the rented period and should be counted 100%. How to correct this other than overriding the shedule E manually, and actually, how do I even do that in turbotax online?
