I have a new client that has a rental property since 2014. The property was depreciated properly prior to becoming my client. I am working on the 2021 Return and entered the asset as I usually do - entering the value of the property, the land, the length of time (30 years/commercial property). Up to this point it works fine and calculates the depreciation matching prior Returns. The problem starts when I enter prior depreciation, suddenly the depreciation changes for this year. I need to be able to have it properly calculating, because the building was "exchanged" (Section 1031). I have not even started on the1031 Exchange since the prior depreciation is giving me an issue. What am I overlooking or entering wrong?
