Hello there, @KathleenW8.
In QuickBooks, you can match using the amount and transaction dates when looking for a match. It's considered a Match if they have the same amount and the transaction date is within 90 days.
You'll see multiple possible matches if there are several transactions with the same amounts that are within 90 days. To give you more details on how QuickBooks handles banking transactions, please see this article: Add And Match Downloaded Banking Transactions.
Let me know if you have other questions.
