Cannot e-file a 0140 X after a Rejected 1040 e-file return

I filed a 1040 and did not check box for "Is a dependent" (I am).  My SSN was flagged as being on another return as a dependent, and my e-file 1040 was rejected.  Instructions were to create an amended return and refile.  Return was amended (became a 1040X) but when I tried to e-file the software error message said you cannot e-file a 1040X if you didn't efile the original 1040.  The saved documents from Turbotax provide date/time stamps showing a return was efiled and rejected.

Since I couldn't efile, I mailed the 1040X to IRS.  I have received a note from IRS rejecting my 1040X because they have no record of receiving my original 1040.

Question:  Should I just delete the original 1040 file and start again, pretend I didn't already efile?
