Shift/enter did not work for me and TT support either. TT finally submitted and GA finally accepted my e-file of S-Corp. Before my last good attempt, I resolved myself to file by snail mail. I went back to TT and set it to file by mail. I printed all of the necessary forms to PDF. Before actually printing them to printer, I tried one more time to e-file. That's when it successfully submitted. I don't know if something changed in TT when I selected file by mail and printed (to PDF) and then switched to e-file, or if TT actually fixed something regarding the "transmissions are not available".
Anyway, I'm good with business filing. Now I hope the personal filing doesn't f-up.
