I bought an office condo for my insurance business this year. How do I depreciate this property?

I bought an office condo this year for my insurance agency business. I previously had been renting a condo. I don't see anywhere to enter information that will calculate the depreciation amount.

An aside, I also have a 2nd home which I rent out and I do see where to depreciate it. I assume that the office condo should be depreciated somewhere in the business deductions.
