I keep having doubt when im wildshaped do i use my profiency to attack rolls or the  beast.........i would say beasts  but not sure?

For your attacks, you use the values from the Beast's stat block:

Game Statistics. Your game statistics are replaced by the Beast’s stat block, but you retain your creature type; Hit Points; Hit Point Dice; Intelligence, Wisdom, and Charisma scores; class features; languages; and feats. You also retain your skill and saving throw proficiencies and use your Proficiency Bonus for them, in addition to gaining the proficiencies of the creature. If a skill or saving throw modifier in the Beast’s stat block is higher than yours, use the one in the stat block.
