I am trying to E-file an extension for a  S-Corp return. I follow the following steps
1. Run efile extension wizard
2. Click next and it passes the Lacerte validations. 
3. Click on "send efile Returns Now" 

However the transmissions fails. The error I see under activity is "US EXT. transmission failed". When I hover on this error it says "The submissions is a duplicate of one that was previously received." 

Any help on how to resolve this?
