You can follow the steps provided by GraceC to achieve what you need. But instead of using Account Receivable in the Account column, use a different account such as income. Moreover, blantonbuild is also correct.
It just depends on you on what solution you'd follow, since both suggestions will get the same result. For guidance, I suggest you contact your Accountant for advice.
