Log onto "MyAccount" at Intuit.  You may have to switch from the 'new' account set up to the old.  Search for 'efile' & it will bring up a screen to enter info about your specific client (i.e. SSN).  Click on "all" and see if it shows up as accepted.  The first five of the SSN will be redacted, but the last four will show as proof.
