According to https://www.irs.gov/publications/p946:
Residential rental property recovery period can be 40 years if placed in service before 1/1/2018. Mine was placed in service in 1992, and my accountant has always used the 40 year depreciation. I'm using TurboTax for the first time, and it only does 27.5 year depreciation, making my depreciation $0. How can I get it to use the 40 year depreciation instead?
