You need to go to where it says "Sign In / Create your account." Since you have never done this before, you would need to create a new account.
Ok, it says I need a bank account number but I don't actually have a bank account yet. What do I do?
Well since it is after March 1, 2013, you are required to get your payment with direct deposit. You do need a bank account in order to receive your payments.
I know but I don't know what to do. How do I get a bank account?
