I resolved issue to the same error message. Check line 18 a on 1040. For some reason PYEI was on my 1040 submission. Eliminate PYEI got rid of this error for me. Good
LUCK!
Business Rule X0000-005 - The XML data has failed schema validation. cvc-complex-type.2.4.b. The content of element 'PYEarnedIncmEICGrp' is not complete. One of '{"http://www.irs.gov/efile":PriorYearEarnedIncomeAmt}' is expected.
The following information may help you determine the form at issue:
