I have a 1040 file with a schedule c, d, f and several other forms.  I have electronically filed and received a rejection stating that ending inventory on Schedule C can not be negative.  The Schedule C business does not have inventory, and these fields were not used on the return.  I entered 0 in both the beginning and ending inventory fields and resubmitted.  I received the same error.  When trying to run the federal final review this feature went through the first 3 items and hung.  It keeps cycling through the same 3 items if you keep pushing the "next" button.  I worked on this return over several days, and only encountered this issue on the last day.  Something must be wrong with the file.  Is there a way to repair the file without reentering all the data or filing on paper?  This is an 50+ page return so I'd like to fix the file if at all possible.  Does someone know of a way to do correct this issue?
