Have a rental property that was placed into service in 2010...we have taken depreciation every year. We have always filed using TurboTax, and have never had an issue until this year. Residential Real Estate is depreciated for 27.5 years using a Straight-Line method. By my calculations there should be anther 20 years of deprecation left. While trying to complete 2017 taxes using TurboTax Premier Online, it will not apply the depreciation. A major remodel's depreciation is being applied, but that is a less than a 1/6 of the depreciation that should be applied. Any ideas on why, or where, my depreciation went.
