Would this require special handling in Turbo Tax?
That depends. If you will be reporting the sale in the "Sale of Business Property" section, then YES, special handling is required in order to indicate conversion to personal use on the closing date of the sale and stop depreciation on that date.
I am using Deluxe and there is a question about whether If the business use percentage varied over the life of the asset.
No, your business use percentage did not vary. Not ever. Once it became 100% business use, it remained 100% business use for the entire time it was classified as a rental.
