Where to find the total depreciation taken on a home in the prior year return?

In reporting a sale of home, I need to find the depreciation taken on the home in the prior returns. In my 2017 return, Depreciation and Amortization Report, I see a line for "residential". There are two columns "Prior Depreciation" and "Current Depreciation". Should I add the two numbers to obtain the total depreciation taken so far?
