I haven't experienced this myself with my 2020 taxes. (I have three rentals) However, I have experienced it in past years. The solution that worked for me was to work through each individual asset one at a time,start to finish. I didn't change, enter, or delete anything. I just "worked it through". Upon completing the assets/depreciation section and clicking the DONE button, all the numbers showed up as expected on the summary screen then.
