Hi there,

I appreciate you posting your question in the Community. 

I'll be happy to share more info about the Bank Feed. The Excluded transactions are those that are not added to your QB bank account history. This happens when you delete the transaction in QuickBooks. If you remove the transaction from the Excluded tab, you won't see it in QB anymore.

To see which deposit matches with what, click on the transaction in question and you'll see the CATEGORY OR MATCH column. From here, you can start matching your transactions. Keep in mind that you must open the transaction to review possible matches. To stop the automatic matching of you bank transactions, I recommend you to take a look at the following article:

The article will show you how to edit, create and set bank rules. Through this article you'll learn how to stop your transactions from automatically syncing. Give this a try and let me know how you make out. There's another article which I think you'll find very helpful https://quickbooks.intuit.com/community/Banking/Add-and-match-downloaded-banking-transactions/m-p/26.... This article goes over everything about bank transactions and the Bank Feed. Check it out and let me know if it's helpful.
