Exactly what should I be pinching off a basil plant to make it not get

I think your question may have gotten cut off but I think this tip is what you're looking for-

As soon as flowers become evident, pinch them off so the energy in the plant stays diverted to foliage growth. If the basil plant is growing vertically, pinch the leaves from the top to encourage lateral growth. Use the pinched leaves or dry them, so there’s no waste. Basil grows quickly, so even if you don’t want to use the leaves right away, keep trimming back the plant when it gets large and bushy.

Thank you!

To keep plants bushy, you pinch the newest set of terminal apex leaf pair off... this stimulates the lateral bud (on the stem sides) to sprout new growth.
