The IRS rejected my return for the following reason:
A Dependent SSN in the return must not be the same as the Primary or Spouse SSN on another return where 'PrimaryClaimAsDependentInd' or 'SpouseClaimAsDependentInd' is not checked.
Can you tell me what "another return" means or where I might find the 'PrimaryClaimAsDependentInd' or 'SpouseClaimAsDependentInd' that is not checked?
