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 during the day on Monday. And it may or may not be fixed on Monday.
Hold off for now, and something may reset in the next 24 hours that lets you efile soon. Or at least more info should be coming on Monday.
Give them a chance to work on it. It may or may not be fixed immediately. The filing deadline is still 24 days away. I personally wouldn't print and mail unless it approached the deadline with no fix. If it's going to take them a while to fix, they usually put out a containment FAQ with more info and possibly a place to sign up for email notifications.
Or if you want to phone Support on Monday here's how.
Hours are 5AM-9PM Pacific (8AM-12 Midnight Eastern) 7 days.
