Hi Sheldon, if you haven't categorized the transaction yet, you'll have to exclude it and manually edit the correct date within the file before importing it.
However, if you have categorized it, go to your Chart of Accounts and open the Account History for that specific account. Find the transaction you need to change, click on it to edit the Date field, and then select Save to apply the changes.
Please note that the Banking tab will still show the original bank date. But reports will use the corrected date.
You can refer to this article for more information about editing transactions: Find, review, and edit transactions in the account history in QuickBooks Online.
Please let us know if you require further assistance.
