Thanks - I tried that and gave up after a long wait... will try again this week.
There seems to be a simple bug - when you have a zip code longer than 5 digits, the e-filing status does not update correctly (within the app and outside) and causes the whole process to fail.
There is also a second bug, where the desktop app, does not ask you if you have filed the taxes - when you begin the process to amend. This causes issues with the way the 1040-X gets populated...
I wish there was an easier way to submit a bug report.
Thanks to @CarissaM @SForrestLO @MichelleLO for sparing the time to try and help.
