Explanation:

• Verb tenses show the verb forms (such as went, go, will go) that English speakers use to give time frames for the past, present, and future in their language.    

• We use the present perfect tense present to talk about the action that has taken place at some specific particular time.

• It uses auxiliary verbs and past participle(Verb 3) for the main verb i.e. root verb + ed.

• The present perfect is used to indicate a relation/link between the present and the past. (Past in past)
• The time reference of the action is before now but not specified, and we are often more interested in the result than in the action itself.

• But we use, the present perfect continuous tense employed in a sentence to indicate an action that started in the recent past and is continuing in the present. (Past in Present)

• It is also referred to as the present perfect progressive tense as the action progresses from the past to the present.

• Here, "how long have you been watching TV?" alludes to an action performed during a period that has yet not completed/still continuing.

• And "How many episodes have you watched?" Describing an action that started in the past and is continuing in the future.

Therefore, the correct form of verbs using present perfect continuous tense or present perfect tense can be written as follows-

1) "how long have you been watching TV?"

"How many programs have you watched?"
