I have same issue as rrollins. Turbotax Icon bounces then a box opens briefly "checking to make sure everything up to date" and then ... nothing. I am running OS Catalina 10.15.3 on an iMac. I have deleted and reinstalled and redownloaded and reinstalled. No error messages, just nothing. I started my taxes a few weeks ago and same thing happens when I open the turbotax file. Turbotax 2018 works perfectly still.
