Investors & landlords

Hey, thanks for replying.  Not the question though.  I get that you can set the ratio by percentage of rooms rented or by percentage of square foot.  I don't see anywhere to enter this in Turbotax.  I already did  my deductions and entered the mortgage interest, insurance, property taxes under my personal deductions.  Now I am entering my rental income and it asks me for the same info.  I want enter what percentage to distribute from the data already entered, but I can't find that anywhere.  How does tubotax handle this split?
