I owe the ten percent penalty for a early 401 withdrawal how do I find out who to send that too

The 10% penalty will be calculated as a tax and deducted from your credits. If there is a balance due on your tax return, then your payment will be sent to the Internal revenue service. The mailing address will be printed on your payment voucher page. This page will print along with your tax return.
