Hello @usercollin-kerschner,
As much as I'd love to offer help and fix the incorrect upgrade of your subscription, we've got a separate team who can better address this concern of yours.
That being said, I'd recommend contacting our Customer Care Support directly from the Help menu. Let me show you how.
- Go to Help.
- Select Contact Us.
- Enter Cancel the upgrade in the What can we help you with? field.
- Click Continue.
- Chose a channel where you want to connect with our specialists.
With their tools, one of our specialists can work with you and hopefully cancel the incorrect upgrade of your subscription.
On top of that, I've also included this reference for a compilation of articles you can use while working with us: Account Management for QuickBooks Online.
If there's anything else that I can help you with, please let me know in the comments. I'll be here to lend a hand.
