Client has a net loss of $6k on his Schedule C, but we are electing to still pay SE taxes under the "Nonfarm Optional Method"... which triggers the EITC to populate.

There is an e-file error stating that the return is ineligible to e-file due to "all earned income for the Earned Income Tax Credit (EITC) is calculating from undocumented sources" ... what?! Not sure what that even means...? Is there a way around this error so I CAN e-file? Mail is so backed up.... Thanks!
