things get lost in the mail. did you use a method where you get proof of delivery.. highly advisable. what does IRS show for refund status. it would give us a clearer idea of how to respond. however, you do have the options of calling the iRS or downloading a transcript of the return. if there is no transcript, either the IRS never got it or it hasn't been processed as yet. if the IRS has received your return but has not gotten around to processing it, efiling a second copy will only delay your refund
