Good morning!  That diagnostic is a recently reported issue that our developers are working to correct.  In the meantime, you should be able to bypass the diagnostic and e-file by following these steps:

1. Highlight the client from the client list.
2. Go to the e-File menu.
   
3. Select e-File Support Tools and then choosing Disable e-file Error. 
   

Once the e-file diagnostic error checking has been disabled, the return can be transmitted.  Our customer success team can be reached at (800) 933-9999 should you have any further questions or issues.  Thank you, and happy tax season!
