Enter your rental property information through the TurboTax guided questions (or choose edit rental property if property is already listed) until you come to a screen that is titled, Your "rental property name" rental summary. You will enter your rental property house here under "assets/depreciation".
It's possible that TurboTax automatically carried forward depreciation from prior years returns. You can check this by revisiting your Rental Property and checking on Assets/Depreciation. Also you can view any depreciation in the forms mode look at the depreciation schedule there.
Depreciable basis : Generally, depreciation on your rental property is the based on the original cost of the rental asset less the value of the land (because land is not depreciable). The original cost can include various expenses related to the purchase of the property. If you make a capital improvement to the rental property, you will depreciate it using the same useful life of the underlying property. If you don't know the original house and land separate costs, you can use the percentage of house and land to total value listed on your property tax bill to allocate the original cost.
