What amount do I enter in the Depreciation After May 6, 1997 field?

I see from a previous question that I have to enter all depreciation for the portion of the home I used as a home office every year it was claimed, but I'm struggling to find out what that number is for each year. I claimed home office exemptions from 2016 through 2019 and sold the home in 2020.

What field from previous filings should I look at to find out what was used as the depreciation amount for each of those years?

I thought it would be the "Depreciation allowable" amount from form 8829 on line 41 (shown in the image below), but I'm not certain this is correct
