I'm trying to unlink my paypal account as it seems to be confusing the figures. I cant seem to find a way of doing it and cannot find anything in the help section

Welcome to the Community, @rcolvin.

You're referring to the Paypal account in the Banking page, correct? If so, here's how to unlink or disconnect it in QuickBooks Online (QBO):

1. In QBO, go to the Banking menu at the left pane to get to the Banking page.
2. Select the Paypal account and tick the Pencil (edit) icon. 
3. Place a checkmark in the Disconnect this account on save box, then hit Save and close. 

For more information about the process, please refer to this article: Disconnect or delete an account from the Downloaded Transactions page.

On the other hand, if you're referring to unlinking or disconnecting a Paypal app, consider checking out this article for the detailed steps on how: Disconnect an app.

Please let me know in the comment section if you have any other issues or concerns. I'll be more than happy to assist. Have a great day!
