If the problem is the CPA used life x and method y while TurboTax is using life a and method b then this is due to the CPA using a different category of asset than what you selected.
tell us the life and method the CPA used and perhaps we can suggest the category to use in Turbotax. This assumes the CPA used a proper life and method. if not this is an issue that has to be resolved by either amending prior returns or filing form 3315 for which consulting a pro is advisable.
