I will post a screen shot in the original post. This will tell you the amount of depreciation in PRIOR years. You will always have to add the current year to that amount. So, for 2017 take the amount of Line 18, Schedule E and add it to the amount. Since you will have no more depreciation before the sale, you will not have to do this for 2018. You will have to enter the sale in Sale of Rental Property, since it won't be rented in 2018.
