Sorry you had all that trouble. I would like to see members of the Tech Support team assigned to look through the community forum on a rotating basis, but I haven't seen one post in the forum in several years, and even then it was very rare. Granted, I don't see every post, but I see a lot.
In my forum search of that error, I'm not sure there is a "one size fits all" solution. Some West Virginia filers were getting that error in early filing season and a user anecdotally said for him it was a PDF they were attaching was too large--reducing the size worked for him. A couple others said they adjusted their browser trust zone settings, while others said that didn't work for them. So I'm not sure anyone knows what "THE" solution is.
If you'd like to relate your experience to Intuit, you can contact a liaison in the office of the President of Intuit. They say they will get back to you in one business day. The contact form is at the following page:
