Bank transactions have uploaded incorrectly whilst doing the manual upload. How can I get rid of them and re-upload the bank transactions? please.

Welcome and thanks for visiting the Community, @susan-lea-gerrar.

You can delete the incorrect bank transactions, then manually upload the right ones again in QuickBooks Online (QBO). There are two ways on how to delete them. Here's how:

If the transactions are still in the For Review tab:

1. In QBO, go to the Banking menu at the left pane to get to the Banking page.
2. Proceed to the For Review tab, then select the incorrect bank transactions.
3. Click the Batch actions drop-down and pick Exclude Selected.
4. Now, go to the Excluded tab and place a checkmark on the transactions.
5. Tick the Batch actions drop-down again, then choose Delete.

If they're already accepted or matched:

1. Go back to the Banking page and click the In QuickBooks or Reviewed tab.
2. Place a checkmark on the transactions, then tick Undo.
3. After that, follow the steps 2 to 5 above to delete them.

Once done, you can now manually upload the correct transactions from your bank. For further guidance with the process, please refer to this article: Manually upload transactions into QuickBooks Online.
