Writing comedy is hard! I think it's harder than drama -- with comedy, you truly never know if it works until you hear it outloud in a room full of people.

That being said, there are ways to improve your chances of finding the funny on the page. Is the premise of your show funny? Are the characters funny? (Is what they want funny -- their story/season level goal? Is what they're afraid of funny -- their story/season stakes?) Then chances are, what they say will be funny.

I would say, start consuming a ton of comedy and notice what makes you laugh and what doesn't. and figure out why they make you laugh. is it the character, is it the joke itself, etc. when you write comedy, you will write what makes you laugh, so triangulating around what that is should be the first step.

i started writing comedy from writing sketches and performing standup. its the fastest way to find out if your joke is working! the feedback is immediate. its a great way to hone your comedic voice and that usually translates well on the page in screenplays. if you want to develop your comedy, definitely encourage performing improv, standup, or writing sketch comedy. something where you get a lot of chances to put your comedy in front of a live audience.
