@Carl Carl, thank you for your response. Let me clarify the situation. The furnace was put into service on 11/25/14 and 50% was depreciated in 2014 while the remainder was over 15 years. The Cost was $3,800 so $1,900 was applied in 2014 and the remaining $1,900 at $127 p/year. Therefore there are 8 years remaining. The same applies to the A/C unit put into service on 04/27/2017 though the numbers are different. There are 11 years remaining on the AC unit. So TurboTax asks if I took the 50% in the year the improvements were put into service and them applies a 5 year depreciation to the remaining expense thus indicating that the improvements are fully depreciated. The depreciation schedule was created by my accountant and I cannot ask why he used 15 years vs. TurboTax using 5 years. So my question is: Can the I override the TurboTax calculation so that I don't lose the remaining depreciation, which totals $3,528
