If I were you, I'd focus on just losing weight for now, while keeping the protein level according to the targeted weight.
So 0.8-1g protein / pound of your desired weight, not the current one. So let's say you aim 180 lbs, that means @ 140-180 grams of protein per day.
But imho, protein powder and any fitness supplements bring marginal results, and most of it is just overhyped, overpriced bullshit ( except steroids )
Stick to a caloric deficit, eat healthy and unprocessed foods to make it easy, and exercise regularly ( at least 3 times a week )
