Not an individual return.  I filed the 1065 extension.  Not sure why getting error message.  I have the complete partnership file ready to efile but it won't allow says duplicate SSN/EIN.

I tried to delete the first file - no can do.

I tried to edit the EIN on the first file so not a duplicate - no can do.

Any suggestions?  Other than re-entering ALL that data .. on a time crunch.
