Thank you for joining the thread, @v1967.

This issue happens if the new account was connected to the old bank instead of creating a new bank from the Chart of Accounts. To start with, let's make sure that the new account was set-up correctly from the chart of accounts.

1. Open your QuickBooks Online account, then click on Accounting at the left pane.
2. Select Chart of Accounts and review the account from there.

After we have to exclude the entries added from the banking page and import them to the correct account.

To exclude the transaction/s:

1. Click on Banking at the left pane, then look for the account where the entries are uploaded.
2. Go to the For Review column.
3. Select the transactions you want to delete.
4. Tap on the drop-down arrow under Batch action, then choose Exclude Selected.

Once deleted, you can import those transactions to the correct account using our WebConnect file. You can get the detailed steps in this article: Manually upload transactions into QuickBooks Online.
