I have a character at her birthday party that as he says hello to someone who has done her wrong... she has a "flashback" of the incident and then she goes into a "selective" consequence that she wished she had given them at the time of the incident how would I break that into a "scene heading" and then an action description.

Again... very new at this so any suggestions are so very appreciated....

thanks

The flashback part is easy. You just write it within the scene. How to make it clear that she's having an I-wish-I-thought-of-that-at-the-time moment is up to you. Here's one way.

If your flashback finishes the scene, you don't need END FLASHBACK, just start the next scene as normal

INT. HOUSE - DAY
Blah blah birthday party blah blah.

A sees B walking towards her.

A
Hello, B

FLASHBACK

Location if you need it - X weeks/months/years ago

B
Nasty put-down line

A
Even nastier and far wittier comeback

END FLASHBACK

A (V.O.)
I wish.

B
Are you OK, A?
