Investors & landlords

so does Turbotax do that for you?  For depreciation you have to input the percentage of time used for a business.  So it's doing that math for you.  But the other expenses I would have to do that math and only input (in my case) 80% of my actual expenses correct?  I also read that if I use it for personal use for more than 14 days a year and rent it more than 15 days that my allowable deductions is limited to my gains.  Is that correct?  In my case I have a net loss than I would have a $0 on my K-1.  But turbotax put down a large loss on my K-1.   thanks for your time.
