When do I ask the court this, at the committment hearing (if there is one), or in my Motion to Vacate, or both?

I actually won a small amount of money in a lotter scratch off. The Purge and Income Deduction order was made on June 4. I want to cash this scratch off and use it to pay my Purge. Would the Lottery Administration be on notice to withhold any winnings and if so, would it go towards the Purge or towards arrears?
