Show me the same expression of the underlined~

No, "been" is a helper verb, you need a verb to complete the sentence.

You could say "what have you been doing?"

But we always use , 'where have you been" "how have you been " they don't correct? if correct so why " what have you been" is in correct?

Where have you been?: present perfect, "been" is the verb of location.

How have you been?: elided from How have you been doing? This is a common idiom.

What have you been?: Not an idiom, only appropriate in questions about costumes and such. In general conversation, it is implying that someone isn't a person.
