Hello there, mikeotaylor. I appreciate you for getting in touch about this.

I see can the importance of using the receipts forwarding to work for a verified email in QuickBooks Self-Employed. And, I see you've been with our support team, and I wouldn't like you to experience that way. 

Since you're still experiencing this problem, it would be best to contact our specialist. This needs to perform some investigation using their tools in a secure environment. You can utilise the Assistant from the top bar to get another specialist and work you with the issue.
