I've tried to google and it wasn't really clear what I should do. I won a decent amount (up over 600 on the year) and I'm wondering how I should go about withdrawing. They make you fill out a W-9 on the site and it there's a box that you check or leave blank that says "I am subject to a mandatory IRS withholding of 24%." Is this basically if you don't wanna worry about paying later on during tax season? Any input from those that know and have done this would be greatly appreciated.
