Hello, @SkyFlower.

Welcome back to the Community. Allow me to elaborate a little more about my earlier post. I was explaining bank rules for both QuickBooks Online and QuickBooks Desktop to sbraver to help clarify what can and cannot be done with that feature.

As for connecting PayPal to QuickBooks Desktop, you can integrate that platform via a 3rd party app. Because there are many different apps in the App store, my best recommendation in this situation is to check out the website to find a provider that best meets your needs in this regard. You can reach that site via this link. 

I hope you find what you're looking for. If you have any additional questions about the information I've provided, please feel free to reach out to me here in the Community.
