Hi there, @Sharon98.
When creating bank rules in QuickBooks Online, you'll need to make sure that the description that you've entered to the rule is specific to the entries that need to be auto-matched. This way, the bank transaction will be matched to the accurate entry in QuickBooks Online.
However, if there are multiple possible amounts that can be matched from your downloaded transaction, the system will automatically match the entry that meets the conditions that you've created.
If the entry that was matched is incorrect, you'll need to un-match it. After that, you may manually add and match it to the right transaction. For some instances, that entries fall into multiple rules, you have to manually select them too. This scenario may happen to your future transactions if the rule isn't specific.
Lastly, I'd like to share this reference that you can check out to guide you in managing your bank transactions together with smooth reconciliation: Categorize and match online bank transactions in QuickBooks Online.
You can always find me here if you have any other questions about this or with QBO. I'll be around for you. Take care!
