what you would probably need to do is upload the .taxfile2021 file. to the desktop. then use overrides to get the depreciation and 481 adjustment right. you may end up with a mess on your hands. there will be no accuracy guarantee due to overrides and you'll have to mail your return so do not expect to hear anything about it for 6 to 9 months (or more since this may require special manual processing). you would probably need to delete the original property. and then enter each component as a separate asset. Turbo tax doesn't really have the means to enter the asset's depreciation history so future years may also present an issue.
