So im building a new players handbook fighter and the Protection feat isnt showing up
The Protection fighting style feat? That feat is in the 2024 Player's Handbook, so to use it in the character builder, you'll need to either own that book or have access to it through content sharing. If you don't own that book, you'll only see options from the Free Rules, which for fighting style feats include Archery, Defense, Great Weapon Fighting, and Two-Weapon Fighting.

If you do own the book, check your entitlements: https://www.dndbeyond.com/account/licenses
If you don't, then you have to be building the character within the campaign in which it's shared with you.
