I did an electronic extension for a federal return because I wanted to extend the state.  It's automatic.  I would like to go ahead and file the federal return now.  When the extension was filed it was marked for electronic fund withdrawal of the balance due on the due date.  If I go ahead and file the federal return now, is that going to cause any problems?  Like, the tax payment being withdrawn twice maybe?  Anyone know how that would work?

TIA
