I just successfully e-filed my GA 700/1065 forms. I tried earlier this morning and received the same error as before. I had also checked that my program was up to date this morning, which it was. I simply went back into the TT program after 1800 ET (6pm) , which was still open on my PC, and hit transmit. Bingo it worked.
My bet is the problem was on TT's back-end/gateway that handles the e-filing as nothing changed on my PC between for the past couple of days. I didn't even have to close and reopen TT.
I just checked here: https://form-status.app.intuit.com/tax-forms-availability/formsavailability?albRedirect=true&product... and the page now shows the forms are ready.
Good luck. Please report back if you can e-file to give others an idea whether this was a random event for me or if TT has resolved the problem without informing us.
