After our tax preparer retired last year, I opted to use TurboTax Desktop for this year's tax filing. However, I've encountered a problem with how TurboTax processes straight-line depreciation for improvements on our rental property. Previously, our tax preparer used a spreadsheet to calculate the depreciation values, which were then entered on the Schedule E form using a tax software other than TurboTax. This method allowed for the rental's depreciation over 27.5 years, a process easily duplicated in TurboTax. Yet, we've made property improvements over the years, traditionally deducting these over 10 and 20 years. TurboTax Desktop does not seem to allow setting the depreciation lifespan for these improvements. Notably, some improvements are six years into depreciation. Still, when added to TurboTax, it suggests they are fully depreciated, implying it may be using a five-year depreciation model or a different approach. How can I adjust the depreciation life for these improvements to 10 or 20 years in TurboTax?
