Rental situation for partial and full house.

I have rented a room and bath to my son for the last 10 years in the house I own.  I've use TBTx desktop to for filing that income.  So, last year, my son rented his room for 4 months (121 days) while I was living in it also.  We both moved to different locations and I rented the entire house to new residents for the balance of the year (245 days).  I started prepping the house for the full rental in January with the rental broker, if that makes any difference.

How do I define my personal use days of the house?

How do I separate the rental percentage for 4 months, and the full (100%) rental spare for the additional 8 months?  Would I need to enter or show two separate rental incomes?
