Same here. Could not efile federal and state (IL). Spent over an hour on the phone and found I was able to efile federal by itself. But when I went back to efile state, same response. Transmission failed, update to program required. I've done all the updating, rebooting computer, rebooting router, waiting several days and trying all again that I can do. Nothing works. I've already paid the fee to efile. It is very difficult to find any information that is helpful. I have a downloaded version from Amazon for Mac. Was very frustrating speaking with "specialist" at Turbo Tax. Kept having to repeat, repeat, repeat the issue and what I've done to solve the problem. I've been using Turbo Tax 15 years and I've never had a problem. I've spent hours and hours of wasted time on this issue and need to get it resolved ASAP. Very frustrating experience.
