OK - while clicking "Clear and Start Over" did not cause the consent form to be presented to me again at the beginning of the process, the form did show up again at the end during the "Review" process. I don't know if clicking "Clear and Start Over" or calling customer service had anything to do with this happening or not. So this time I was able to click "Decline", and the permission letter does not appear in the PDF of my return. So I think it's all OK now.
