Mortgage Interest, Insurance, Taxes on Duplex

I own a duplex and live in one side, while renting out the other. I only have 1 statement for property taxes paid, mortgage interest paid, and insurance paid. Turbo tax asks for each of these items as a portion of the rental property and then I can enter my personal later.

 

How should I handle this?

 

Should I prorate the amounts (cut the amounts in half and enter half in rental and half in personal)? I am scared to do this because the 1098 won't match.
