Turbo Tax has terrible customer service - can't transmitt via efile Michigan returns 2//23/2020

My Federal went through e-file after I unchecked state. My Michigan return does not transmit? I came back to state and updated on-line a dozen times over two days to no avail on 2/21, 22 & 23/2020. I have never had that problem in 15 years of using Turbo Tax. I am a retired 40 IRS Agent Appeals Officer and adjunct professor in taxation - I know what I am doing with my simple tax returns.
I can't find a 800 number or support email address to send a message to TT? Turbo Tax has declined very badly this year! Time to get Tax Cuts from H&R unfortunately. I reported Intuit to the Michigan Attorney General’s Office for fraud – TT took my $25 and no response via customer service.
