Where do I enter W2G if I am a professional gambler? I dont think it is right to enter it in the less common income because it won't subject to self-employment tax.

I need to report it as a self-employment income so I am including the W2G incomes on the schedule C instead, but I do not know where to enter the payer's info on my schedule C. should I just ignore the payer's info? Can anyone help?
