Turn system for blendspace

Hello I have a problem with rotate system. I am using Blendspace 2d (not blendspace 1d) and controller yaw is off. When I am looking the charact from the front from the anathor side the character isn’t turning to your camera view side it is glitching. But I want do same system with last of us. Viz when I am looking the character from any side character should turn to your camera view side slowly and with animation. But not automatically. It should rotate when I press w/a/s/d. How can ı do this system (same turn system with last of us )
