Investors & landlords

When I did the above, one place in one of the help blurbs told me to prorate the gains between the business property and not sections.  So, I put 5/9 in the business section. In the home section, I tried to put in the other 4/9. It deleted the entry when I said it had been rented some of the time.  Should I put all of it in Business? If not, where?
