how best to depreciate my house furniture in the rooms used for rental (airBnB)?

Hi. I rented furnished one of the two bedrooms in my house for 9 months last year. 

 

I understand that i can depreciate  the (previously existing) furniture in the bedroom at 100%, correct?

 

May I also depreciate at 50% the furniture and appliances (e.g. refrigerator) in common areas? 

 

if so, how do i use Turbotax to calculate such a depreciation? is it 5-year?
