Business & farm

Thanks for the quick response.  Unfortunately, I think this advice has me going through schedule E.  I'm trying to use schedule c for my Airbnb business.  I did this last year and was able to depreciate my personal residence for the percentage time that i rented the house.  I was able to depreciate the property as a personal residence for 27.5 years.  When I try to duplicate this with turbo tax on schedule C, it does not give me the option to select "residential property" - which is what I used last year on schedule C.  The only option i have is to select "non residential" which depreciates over 39 years, giving me a much smaller deduction.   I'm stuck..
