Hi there, greenenvyhairroo.
I'm here to help find out why the receipt isn't matching with the transaction on your Banking page.
There are some possible reasons that could prevent the program from matching the receipt:
Once the transaction shows R and it should not be reconciled yet, you can remove this from a completed reconciliation. You can check this article to see steps: Undo and remove transactions from reconciliations in QuickBooks Online. This will change the status of the transaction to start matching the receipt.
If the receipt is not affected by possible reasons above, I suggest to manually find the receipt by clicking the Find Match option. Then, select receipts from the Show drop-down menu to show all the possible match transactions.
For additional information, you can refer to this article: Categorise and match online bank transactions in QuickBooks Online.
You can also click this article that will guide you on how to reconcile an account to keep your books balance: Reconcile an account in QuickBooks Online.
