Thank you for joining the thread, @gulfsidebooks.I'd be happy to assist you with this.

In QuickBooks Online once you deleted an account the transactions will still remain. So I agree with you, when you want to remove those transactions you have to clear it manually.

Please keep in mind that deleting a transaction is irreversible.
 

Here's how:
 

  1. Go to the Banking menu and select banking.
  2. Select Go to register link.
  3. Locate the transactions you'll want to delete and double click.
  4. Click Delete.
  5. Then select Yes.
