Did you try:
Thanks for reaching out to the Community, @nplumb. I'd be happy to assist you with reaching support.
As @Lexiesmemere mentioned, you can reach the QuickBooks Online Customer Support team from within your account. Should you be having issues with reaching an agent with these steps, I'd recommend trying an alternative browser.
Of course, the Community is also here and happy to help you.
Please let me know how it goes as I want to ensure that you get the support you need. Wishing you well.
