Is this sentence properly written. Where have you being? or Where have you been?
The verb 'be' is what we call a 'non-progressive verb' and can not be used in the continuous or progressive tenses.

In English we can't say:

'I am being' or in question form:

'Have you being?'
hmm, how 'bout I'm just being logical, Chris?

'Where have you been?' is correct.
When using a verb in the Present Perfect as you are (ie: using have + verb) the auxillary verb is have which is the one you conjugate, followed by the past participle of the verb.
