I purchased a home last year and rent out one third of the house. How do I set up depreciation on the portion I rent?

I short term rental a portion of my house I just purchased.  I rent the bottom floor as a short term rental and live on the second and third floor.  1/3 is rental and 2/3 is my personal residence. Do I need to depreciate this property and if so how do I set up in Turbotax?
