State tax filing

I have been waiting to file my taxes because there have been so many glitches regarding the state returns. I assumed any problems would have been resolved by now since there's been issues going back to February. Apparently some CA filers are still having problems filing. There was a CA update to TT yesterday, but think I'll wait a little longer before filing. I just don't understand why the latest recommendation is to print out state returns and mail them rather than e-file through TT!
