If it was converted to a personal residence, you do NOT report it in the "Sale of Business Property" section. You report it as the "Sale of Home". Be sure to look for the question that asks if you ever used part of the house for a Home Office or rental, because that is where you will enter the depreciation.
As for the Passive Loss Carryover, one option is to fill out the rental section for Schedule E, say it was rented for 15 days, enter the Passive Loss Carryover, and enter zero for everything else (including don't enter assets). If you DON'T have any other Passive Income or Losses this year, the other option is to enter it as "Other Income" as a negative amount. However, I am unsure of the exact location of that in TurboTax.
