Solution 5/20/20: right click on the TT icon, select "Properties", then "Compatibility" tab, then check the box "run this program in compatibility mode for:" then select Windows 7, then run as administrator.
In my case I didn't have to select "run as administrator" but apparently some do.

Turbotax 2019 started crashing any time I tried to modify a return beginning 5/14/20. I had no problems since 4/4 when I downloaded TT to my Windows 7 desktop.
