I am having same problem. I went to patch but nothing happens!
Here is a recently updated help article about this Error that may help.
I found a way the patch worked, it makes no sense but I opened my browser in incognito mode. I clicked on manual patch, It opened a screen that said Turbo Tax updating. It finish and I got back into Turbo Tax. I got same message about updating failed but before it gave me an error message I clicked cancel. Then I was able to get into my Turbo Tax. I figured the update would show new date taxes are due but it does not. Still says April 15. Hope this helps.
after many hours of fiddling with this problem I tried the solution suggested by many that worked like a charm. uninstall and reinstall, you won't regret it.
