Can someone help me?

TurboTax Premier 2020 failed to open on iMac19,1 Mojave 10.14.6 after trying.  Apparently the TurboTax app was verified.  I approved execution of copy downloaded from Intuit.  An “error Report” was then generated to Apple? and the app crashed after I approved sending the report.
TurboTax 2019 worked for me last year when I filed tax from this same computer.  TurboTax 2019 and TurboTax 2020 also fail to open on iMac19,2.

Yes, I know that TT is supposed to run on Catalina but can anyone confirm that?

Can anyone confirm that it actually works?

If you get the message "TurboTax cannot be opened because Apple cannot check it for malicious software" then that is caused by the Apple "Gatekeeper" introduced with OS X 10.15 (Catalina).

That has nothing to do with TurboTax and will happen for any application not purchased from the Apple Store.

See this Apple article on this:

And this TurboTax help article:

For older Mac systems when TurboTax will not open.

Be sure that System Preferences -> Security & Privacy -> General -> Allow apps downloaded from App Store and identified developers is checked.

Go to the Applications folder and select the TurboTax application in the Finder and right click with the mouse (or control click) ans select the top "open". That should force the first open. After that it should open normally.
