What is your basis for thinking what your client paid is "like a royalty"?  Royalty, from a tax perspective, generally entails payment in exchange for a license to use a property, typically an intangible property or a right relating to the development of natural resources.

1099-MISC is not applicable to royalty payments made to corporations.
