My courier paid GST on my behalf, how do I make the entry?

[Correct Example]: Paying Delivery fee (including GST) + the GST of the Goods being delivered.
      Enter a negative amount of the Price of Goods.
      Leave the Tax column empty, this is so that GST will not be included for that row.
      Price of Goods (excluding GST) will be deducted from the total, 






[Wrong Example]: Paying for Delivery fee (including GST) + Price of Goods (including GST) (of which was already paid to Vendor)
