You have watching TV too much.
You have watching TV too long.

Do we use much or long if someone spending too much time in watching TV.

 

[MikeNewYork]

Yes, but you must use "been" after "have".

 

[Tdol]

Or You have been watching too much TV.

 

[Barb_D]

"You have been watching TV for too long" is correct if you mean at one sitting.
A person might not watch too much TV in general, but if they are watching TV for 7 hours straight, you might consider that "too long".
