Same problem here. Running Catalina 10.15.7 on a MacBook Air early 2015 using TT Home and Biz 2020.
After a recent security update to Catalina (I think) TT will not print state returns but will print Federal return. Tried the various fixes recommended but so far no luck. Program hangs on print command and I have to force quit.
I had the same problem with 2019 last year but a long call with TT support fixed it somehow.
