Clarification on Adjust Withhold Amount in the Payment Entry

I was reading the page on Adjust Withhold Amount in the Payment Entry and discussion here on accounting for a PayPal transaction fee which leads me to one question:-

When creating a ‘Withholding’ account, what account type (Chargeable, Cash, Payable, etc) should it be (in the drop down list) and where does it sit on the chart of account categories (Income, Asset, Liabilities, etc)?

Thanks in advance…
