If you manually recorded the VAT payment, you can delete it through the Payments section of the Taxes menu. Here's how:
Go to the Taxes menu, then select the VAT tab.
Select the Payments tab.
Find the payment you want to delete, then click the drop-down arrow under the Action column and choose Delete.
