I retargeted my character and now his arms are like this in the animation
WHAT DID I MISS
Retargeting is a multistep process. You have to make sure the pose between your two characters is the same (A pose, t pose, etc) and the hands, etc line up in the same way.
You also need to set root bone to animation, 2nd to animation scale, and rest to skeleton. Check some of the youtube videos on retargeting.
Thank You Very Much @scottunreal
I adjusted my mannequin’s arm and now it is better
