When asked to put in the real estate tax amount do I put in the entire year or just the amount for the time of the year the house was rented?

If the Rental Property was available to be rented all year, enter the total for the year. But if you took the property off the market for some period during the year, enter a pro-rated amount for the days/months it was held as a rental. The balance may be reported as an Itemized Deduction on Schedule A (Other Property).
