Hi all! I am having the same issue and have been on with Turbo Tax support for an hour. It appears that Turbo Tax 2019 will NOT work with MacOS Catalina and this is what is making Turbo Tax crash. Apparently if you purchased your software directly from Turbo Tax there is a way to convert to the online version and file. However if you downloaded from anywhere else, you cannot. And if you downloaded to file for up to 5 returns, you cannot - you will have to pay for them all.
The rep I spoke with was unable to assist beyond that, so I am reaching out to Apple to see if they can get Intuit to roll out the needed update to get the software to work on the OS. Will add an update if I hear anything.
