I've had the same issue for a week and have spoken to two TurboTax specialists on the phone. In my most recent call today, I was told this was a bug and to file by mail.
This is unacceptable: we've paid for the software, it's clearly a bug, and TurboTax should make the appropriate change to allow for the attaching of another file (in my case, another state return).
To clarify, I haven't used the "My Documents" functionality. It seems to me like this should not be necessary; TurboTax is simply failing to attach the other states' returns to the Hawaii one like it should.
