Yes to all.  Having the same problem.  The original return was prepared by taxpayers.  The program wants me to check the original e-file box when checking the e-file amended box.  Doesn't make sense if I did not e-file the original.  I am also checking that the original return was successfully e-filed.  I am getting the F1040-451 error when trying to e-file.  Am I doomed to paper filing since the program doesn't do what it says it will.
