Yikes, I mean to efile the extension 7004 but in error I efiled the corporate and state corp tax return!  The tax returns hadn't even been started!  How could Lacerte have let it go thru with no revenues, the balance sheet out of balance...I got no error diagnostics, no prompts, nothing!  Immediately tried to call Lacerte to possibly unwind this submission; on hold 45 minutes. Had to leave for the day.  Very unhappy with their service these past couple of years.  Anyone have this problem?  How to resolve?  Just submit a paper-filed return?  Would it have to be an Amended Return?  Any way to avoid this in the future?  Thanks for any guidance, can't find any guidance in Lacerte's 'online help' either.
