Happy to have you here on the Community page, @prapsaru.
If the transactions are manually entered in QuickBooks Online (QBO), you can go to the register to delete or remove the duplicate transfer transaction.
Here's how:
- From the Gear icon, select Chart of Account under Your Company.
- Look for the bank where the amounts were transferred.
- Click on View register under Action.
- Tap on the drop-down arrow beside the Funnel icon, then select Transfer under Transaction Type.
- Choose Apply.
- From there, click on the duplicate transaction, then select Delete beside Edit.
- Hit OK to confirm the action.
If the transactions were downloaded from the Banking page, you can undo or exclude the transfer from the Reviewed column.
- Click on Banking at the left pane, then select Banking beside Rules.
- Select the correct bank account from the result, then go to the Reviewed column.
- Look for the duplicate transfer and click on Undo under Action.
- If you wish to fully delete the transaction, go to the For Review column after clicking the Undo button.
- Select the transactions, then click on Exclude Selected under Batch actions drop-down arrow.
