Welcome, and thank you for choosing QuickBooks, Dancram!
When you say came back unrecognized, do you mean they were already added to your register before and then they go back to the Bank Feeds Center like freshly downloaded or uploaded transactions? If this is the case, I recommend contacting our QuickBooks Desktop Support to check why they came back being unrecognized. That way, this won't happen again.
On the other hand, if you've just loaded your transactions, you can categorize and add them to your register. It's normal if there are no matching transactions if you haven't created one in QuickBooks. Another reason is you can't find a match if the transactions entered in QuickBooks were already reconciled.
I can also see that my colleagues have shared some useful articles about bank feeds. Feel free to check them out.
Let me know if you have other questions in mind.
