The mother and father live apart, are unmarried, and share the care of the child equally between them. When the father applied for unemployment benefits, he included the child as his dependent. He hasn't filed his tax return yet. By agreement, the mother claimed the child on her tax return. However, when the mother filed her tax return, it was rejected with code R0000 - the dependent was claimed by someone else. Was the rejection because of the father's claim for unemployment benefits? The state is Illinois, if that makes any difference.
