Software Error with form 7205

I did find the reference on line item 20 of form 1065.  It is set to zero as it should be; however, the software is forcing a form 7205 to be filled out to be able to electronically file.  Since this is set to 0 - there is no form 7205 generated to delete.  I did reenter line item 20 at 0, and save the return and reattach signature sheet, but still cannot e-file.
