I have rental that I rented for six months of the last year. However, I have expenses that 100% apply to the time that the unit was rented. turbotax is cutting these down

1) I don't understand the percentages. They are not based on the percentage of days I have rented the property for most items. 2) I can't figure out how to make sure that expenses incurred during the time I rented the space are marked in full as expenses.
