I also had the same problem, started yesterday (Sat 2/8). I was still having the same problem today Sun 2/9. I called Intuit TT support on 2/8 and was told by that person she had heard from several others about the same problem and to wait. Tried e-file again Sun 2/9 and still had the same problem. If you try to uninstall TT it also gives you a repair option. I tried the repair tool and got an error message with code 1334 (I'm using Windows 10 with a PC download version). So I uninstalled and reinstalled TT, thinking there was a corrupt file on the install. After the reinstall I had the same problem. I found an .exe file on another TT support thread that forces a manual update. Downloaded and tried that with no luck. So I called TT support again and was told it is a widespread problem and common to get the error code 1334 with the repair tool. So there is a software glitch that needs to be fixed. Support gave me a code to use the online version of TT for free, which I did and got my taxes e-filed without a problem, but I had to reenter all of the info. That wasn't too bad because my filing is fairly simple. Time consuming and a pain to do taxes a second time, but it also verified what I had done the first time and came up with the same result. Although it should not have happened this way.
I'm sure they will push out another update soon with a fix for this problem, so looks like you just have to wait or contact support and do your taxes again online.
