My client wanted to mail his Federal Paper Return with a cashiers check for the balance due, which he did today.  However,  he is receiving a refund from ARIZONA and wanted to e-file that.  I filled out the State only form and tried to e-file but was informed  that the Federal Return needed to be received by IRS before it could be e-filed.  Dah!  Has anyone had this experience before who could tell me a way to check if IRS has received the Federal return?  Also, if they have a time line estimate for the Fed Filing! Thanks!
