Thanks for posting to the Community and sharing your insights about PayPal integration, @Elizabeth_Kholkina.
I appreciate that you've already searched for solutions and references. Excluding several operations in QuickBooks itself when adding PayPal to QuickBooks isn't possible this time. Also, there isn't an automatic solution to connect PayPal and remove bank transactions from which the PayPal account is replenished or entries from PayPal itself. I know this is a great way to reduce manual work and maximize productivity that will help you save more time.
In the meantime, you can follow Fiat Lux Asia's workaround or search for third-party applications in the Apps menu that enable you to filter them. From the Apps menu, select the Find Apps tab. Enter specific functionality in the Search field like filter bank transactions. Then review and install the application to integrate it with QuickBooks Online.
Or follow the solutions shared by my peers to exclude duplicate transactions manually.
Please get back to this thread if you have additional questions about managing PayPal transactions in QuickBooks Online. I'll be around to help. Take care!
