As others have said 'ass to grass' is irrelevant to powerlifting, as far as competition is concerned.
Also, I know plenty of people whose deadlift is waaaaay better than their squat. It's not really that unusual, especially among taller lifters.
If your goal is to improve your squat, you can do a couple things. One would be provide a video for us to help you with technique. You may be making big mistakes in your form and stance, and we can help with that. The other thing you can do is share your training template (not just squat day, but all your days) so we can help you adjust it based on your personal goals.
One other thing: you said you're kinda new to powerlifting. Are you new to squatting and deadlifting in general? When I first started training the squat and deadlift, the difference between the 2 lifts was enormous. My deadlift might actually have been twice what my squat was. I was just really bad at squatting. If you train hard for a long period of time, it is likely that your squat will naturally get closer to your deadlift. Right now I've squatted 550 and deadlifted just over 600. But there was a time when I couldn't squat more than 150 to depth, and I could probably deadlift 300ish.
