Children's SSN
My son's federal return was rejected for the reason listed below. I can not find any mistakes in his return. No other family member has claimed his children.
Any suggestions on what I should do?
SEIC-F1040-506-02 - Each 'QualifyingChildSSN' that has a value on Schedule EIC (Form 1040), must not be equal to another Qualifying Child SSN on another accepted return for the same tax year.
