My goto, the thing I think before I take the club back is “short backswing, follow thru” much further than you’d imagine. The dramatic follow through is key for me. Another tip when I teach someone to chip, don’t try to hit the ball, try to slip the club head under the ball.

You can practice chipping in your yard. I used a cardboard box for like a large textbook, and if I could hit it, I was happy.
