I am having the same error when trying to do my daughters taxes - exactly as you described. I'm also in Oregon. I've been trying to file for a week. My tax return with a 1099Q included went through fine.
Would be nice if it gave an estimated date it will be fixed.
Here's a post I found: https://ttlc.intuit.com/community/taxes/discussion/1099-q-issues/00/3582985
It sounds like I should just delete the 1099Q
