No, it has not been fixed.
I am running Catalina 10.15.4 and TT kept crashing during the File phase.
TT always looks for updates when launched. And it says there is no updates. The crashes still happen to the point that it no longer even opens. I read somewhere that you cannot sent error reports, so I reinstalled and relaunched TT and made sure not to touch the error message window. Sure enough TT was able to open and I was able to efile Federal, but still fail every time with State efile. At one point I got the "lldb" message. Most of there time I got the "TurboTax quit unexpectedly" message.
Very disappointed with TT. I used it for years and never a problem. This year, for Tax 2019, it just kept crashing. Some investigation online shows that the crashing problem has been reported for quite a few months already. Lucky for Intuit, thanks to Cvid19, this year's tax day has been extended. Otherwise, users like me won't be able to file before April 15.
