is there a change in turbotax this year as to how to enter rental expenses when the rental is a part of your own personal home?

Hi, I live in a two family, three story home.  We rent out the first floor (1/3 of the house).  I’m entering expenses in the rental section in Turbotax online. Last year when I entered my mortgage interest and real estate taxes, turbotax calculated the percentage of those expenses that apply to the rental (1/3) … but it doesn't seem to be doing it this year.  Is this a change in the software?  Do I need to calculate this myself this year? Will it calculate it later? Or am I doing something wrong?
