This is a known issue that began about mid-afternoon today (Sunday.) Several users are reporting they have been impacted by rejection error X0000-005 . We have reported it to a TurboTax Moderator, but they may not be able to investigate it until tomorrow.
Just hold off for now, and something may reset tonight that lets you efile tomorrow.
Or if you want to phone Support during business hours, here's how.
Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days.
