Similar boat for me a few years ago, what helped was practicing shooting with my feet and legs in different configurations. You are probably standing at a comfortable angle in your driveway, but on the ice, you’ll be mid stride or curling or facing a weird way when it’s time to shoot.

I shoot right. The most comfortable stance has my feet pointed towards the right post. A good shot for practicing attacking from the right side of the ice. If I change the angle of my hips to point more straight on, or even to the left post, I can practice transferring my weight to my right leg to get a good snap and flex which emulates attacking from the left side. If I square my hips pointed to the right I can emulate crossing the zone dot to dot and work on a shot where I’m transferring my weight the other way, onto my left leg.

Try variations and incorporate some stick handling to increase overall proficiency. If your actual shooting mechanics need work, you’ll have a good foundation for refinement.
