Get your taxes done using TurboTax

The Depreciation and Amortization Report contains the original, depreciable, basis as it was entered into TurboTax as well as the current and accumulated depreciation figures.

If the client has been using a desktop (installed on a computer) version of TurboTax, the report can be found in the list of forms in Forms Mode. If the client was using an online version of TurboTax, the form will be found in the PDF that was saved on some sort of media (hopefully) by the client.
