Question: are not being or been?
Answer: As a rule, the word "been" is always used after "to have" (in any of its forms, e.g., has, had, will have, having). Conversely, the word "being" is never used after "to have." "Being" is used after "to be" (in any of its forms, e.g., am, is, are, was, were). Examples: I have been busy.
