As was noted above, the law and the IRS requires depreciation in certain ways. However, there are some options when depreciating. If your prior tax preparer choose one option but the 'default' way for TurboTax does a different option, the program DOES have the ability for you to choose the other options. In fact, you would be REQUIRED to do so; you can't change methods without going through a lot of extra work.
However, we need to be sure that the prior depreciation WAS a proper option. As Carl noted, if you give details about what the asset is, what it is used for, and the details of how it was previously depreciated, we can help guide you to do it in TurboTax (assuming the prior tax preparer used a correct method).
