This year I had the same problem (TT Premier 2020 - MacOS Catalina) as last year (TT Home & Business 2019 - MacOS Mojave) - not being able to print state return, spinning beachball, having to Force Quit TT.
Last year TT support was useless. However, I finally found a solution offered by mloher on Feb 21, 2020. It worked last year this year as well.
1) I tried again to print state forms and ended up with same "stalled" spinning beach ball
2) I then opened Console (in Utilities folder). After approximately 15 seconds, beachball stopped spinning and print dialog box appeared
3) PROBLEM SOLVED - able to print my state forms and/or save as PDF
Thank you, mloher! And shame on TurboTax for another year of frustration!
