Get your taxes done using TurboTax

I checked this with my tax forms and it says all of the forms I need to file are available for e-file. I thought maybe I was trying to file too early, but today is Feb. 12th and e-filing has officially started and I'm still getting the same error. 

I called TurboTax customer support and they said a lot of people were receiving this error but weren't able to tell me why or help me determine which form was the issue. Are there any other options on figuring out how to fix this?
