There might be another account your're subscribed to. We're unable to check that here in the Community. I recommend contacting our QuickBooks Online support. They'll be able to pull up your account and trace the charges.
Here's how:
Click the Help icon.
Click Contact us.
Enter double charges, then click Let's talk.
Select from Start messaging or Get a callback.
Note that our support hours has been moved to 6 AM-6 PM PT Monday-Friday.
I'll be right here if you have additional questions.
