How do I enter Special Depreciation (section 168 K) taken in a prior year on a rental property asset?

There is a field to enter prior years section 179 deduction, but I can't find one for Special Depreciation.  I wasn't using Turbotax in the year the property was acquired, so I need to add the info now.  I want to enter it properly as prior Special Depreciation (rather than just prior regular depreciation) because I'm depreciating the asset regularly for the state return -- NY does not follow Federal rules for Special Depreciation.
