depreciating a portion of personal residence

How do I depreciate my personal residence used for Airbnb business?  Turbo tax only shows options for "nonresidential" real estate.  I had an accountant file for me last year and they were able to depreciate my home as a personal residence with a 27.5 recovery period.  Turbo tax is forcing me to select non residential with a 39 year recovery period - giving me a much smaller deduction.
