I found that info on my 2019 returns as we stopped renting back then.
Just add together the total amounts in the Prior Depr columns and the Current Year Depr columns on the 2019 report, and that will give you the total amount of depreciation taken, that has to be recaptured in the year you sell it.
If the property was "in fact" converted back to personal use on the 2019 tax return, then you may find it simpler to report the sale on your 2020 tax return in the Sale of Business Property section.
do I add the "Prior Depreciation" and "Current Depreciation" to get my taxable total ?
Yes. But I wouldn't call it "my taxable total". It's the total that has to be recaptured in the year of sale. Weather it's taxable or not depends on other factors. Recaptured depreciation is taxable anywhere from 0% if your AGI is low enough, up to a maximum of 25%.
