How to Enter a 6 month rental of my residence?

I rent out my summer residence for 6 months every winter. I use it exclusively 50% of the time, and rent it exclusively 50% of the time. I think I should be able to deduct 50% of my expenses, and 50% of my annual deprecisation. Turbotax wants to treat it as a vacation rental and limit my deductions to the amount of income. I entered 183 days rental use, and 182 days personal use. Where did I go wrong?
