Help me shallow out my swing

Take the club back more to the outside, make sure your position at the top isn’t “across the line” (pointing to the right of your target line), start your downswing from the ground up, making sure you are rotating your hips all the way through. If you’re doing all of this properly, you should feel your hands, and thus the club dropping slightly when they start down. That will shallow everything out.

For the first move down, think about moving your right elbow towards the ball. There is probably some element of your hips moving towards the golf ball (early extension) as well. If your body is in that position you have to get steep to make contact
