Someone else reported the same problem last night but SE tax worked correctly in my test account.
To assist turbotax in troubleshooting, go to My Account, Tools, and choose "send file to agent." This will upload an anonymous version of your file to the tech support database and give you a token number. Post the token number here so I can tell the moderators what to look for.
Then you might try deleting the W-2 and making a new one.
Otherwise, you'll need to contact customer support. Customer support can be reached via Twitter, Facebook or telephone. https://www.facebook.com/turbotax/ and https://twitter.com/TeamTurboTax
For telephone and other support options, see the instructions below.
