I have the same problem, when wanting to efile Federal, CA and NY taxes. I tried the uninstall and reinstall Turbotax route to no avail. Then I discovered 2 steps, one was what I call force update

Which did find an update, that otherwise wasn't being identified when starting TT. This update didn't seeme to cure the issue so it could well be red herring.
The other step I discovered was to efile federal and then state, once federal has been accepted.

So I went down this path and managed to efile the federal, then some 15 minutes later managed to efile the California state. However when it came to NY I get the error "Your transmission didn't go through". So clearly the issue is with NY efiling and Turbotax. I wonder if its the fact that NY doesn't allow tax preparation software companies to charge twice, once for buying the tax preparation software and then charging a fee to efile has anything to do with the poor transmission. I wonder if the same problem exists with other states where they aren't allowed to charge too.
