Two business share the same home office questions

I am using the TurboTax Home&Biz desktop edition.

I have used a small room as the home office for my consulting business for years. I added a new trader business this year. Both businesses share the same home office.  However, there is no entry related to sharing in the entire data-entering process. All I can do is input the home office data twice. Nowhere asked me about how many percentages you are going to use for business 1, and how many for business 2. Maybe my understanding was wrong.

Is the same data entered twice under each business a sharing? If not, how to share?
