I am e- filing a 990 for an entity with an October  2020 year end.   I have entered all of the data into the 2019 module, it validates.  When I try to e-file, I don't have an opportunity to proceed because it says "Federal - Accepted".  I did not previously efile this return.  It is new and I just entered it today.  I filed other 2019 990s (calendar year entities) with no issue.  The only thing different about this return is that I did copy it from another return, but changed the name, the FEIN, and (of course) all of the data.
