It's great to have you in the Community, @sales152.
I've got some information regarding QuickBooks and eBay integration. Currently, connecting them will require a third-party application. We have some available apps in the marketplace that can help you connect two different software easily. You can check them here: https://apps.intuit.com/app/apps/home.
Since we're unable to recommend you what app is better, you may utilize the search engine to find the most helpful that'll automatically sync your eBay sales with QuickBooks Online.
Let me know if there's anything else you need. Take care and have a great weekend.
