I spent 3 hours chasing this with TurboTax tech support and MS yesterday. Here's what I was told:
1. TurboTax changed this year all usernames when importing can NOT have a special character (WHAT??!) in the username or the import will fail.
2. MS said the feature has NOT been turned on yet.
3. MS also said they are now requiring a minimum of 9 characters for usernames or it will fail.
YMMV
