I'm having the same problem, but this response doesn't quite solve the issue.
Similar to the OP, we're renting one bedroom in our condo. For simplicity, let's say the room was rented 180 days with no personal use (so I'll put personal use days as zero).
Now, how do I indicate that just one of two bedrooms was rented when entering expenses like mortgage interest or property tax so turbo tax can "do the math"?
