After you file

Sooo - after I found out that my efile returns were rejected because turbotax software said to file a joint return in light of the fact that my wife passed Mar of 2019 and her ss# was no longer valid, Wala! Bottom line question now is mailing the printed returns even though a message note said in the turbotax filling said not to sent mailings if you already efiled? Does a rejected return notice nullify this situation? I have printed the mail fillings. just don't know whether to mail them or not.
