If the deleted transaction is from the most recent reconciled period, you can recreate the deleted transaction. Then, manually reconcile by marking an R in the account history.
If you want to view the information on the deleted transaction, click on the Gear Icon, and select Audit logs. Or you can view the Reconciliation report under the Reports tab and search Reconciliation report.
Here's how to manually reconcile the transaction after you've re-created it back in QuickBooks Online:
Then, check your reconciliation page once more to verify the ending and beginning balance of the account. You may want to check these links to learn more about Reconcile an account in QuickBooks Online and Fix issues at the end of a reconciliation in QuickBooks Online.

thanks for the tips, if this all works and iam sure it will, i should then be able to reconcile next 1/4 but it will show my accounts out by the amount of the dupliacte transaction, is there any way or rectifying this so the acoounts balance with what the bank account is?
Thanks in advance
Deleting a reconciled transaction will affect the opening balance on your next reconciliation. If the two transactions are deleted and both are reconciled already and would like to keep one record of transfer for that bank account, you may need to undo the entire reconciliation for that month. Your accountant can do that for you.
Once done, we'll need to check if the bank transfer has been recorded correctly in QuickBooks Online before you can reconcile your bank account again.
If you have imported transactions for both accounts and have already entered a Transfer, you can match the imported transaction in both accounts.
If you have imported transactions for both accounts and you have not entered a Transfer, the easiest way to add the transaction is to transfer from one of the accounts and then match the transaction from the other account.
The transferred transaction is matched and you'll be able to reconcile your bank again.
