However, you might be thinking of the past participle of "be" which is "been". "Been" is often used in conjunction with "have" or "has" to form the present perfect tense. For example:
* I have been to the store.
* She has been to the doctor.
You might also see "being" used in some contexts. However, "being" is a present participle and not a past participle, so it has a different meaning. For example:
* I am being quiet.
* She is being helpful.
