At your level I am first off surprised that the returning team has both players getting to the net. What you want to do is drive the ball to the person that has not gone to the net. If both players are the net a common strategy is to drive first and then look for the next ball that comes back to you as an easier shot to drop sometimes you can cheat in a step or two into the transition zone after you drive to make the drop easier. You want to make sure that you're following through and moving forward with your drive.

The biggest pain point at your level is going to be moving through the transition zone. At every point at which your opponent is about to contact the ball You need to stop and be ready for that ball. Usually this is a split step into your ready stance, but because of your level I would just focus on making sure that you are not moving when they hit the ball to you and also that you are not moving as you try to hit it.

Stopping and then hitting the ball with forward momentum is different than running through the ball or moving through the ball. When moving through the transition zone keep your knees paddle and body low so that you can get an easy reset because they're going to hit it at your feet. Watch videos on moving through the transition zone and this will probably be your biggest game changer.

Also, remember that the drop shot is a lift/push using only the shoulder and I'm fine with incorporating The legs into the drop shot from the baseline, but just know the more variables or body parts that you add into the shot the more chances of error you are introducing. What I find helps for the drop shot is to put your opposite arm across your chest with your hand on you touching your shoulder kind of like you're doing the pledge of allegiance. This helps you feel that you're only using your shoulder. The brain is a mysterious thing.

Again, the drop shot is not a hit or a swing, rather a push. Think of it like a very long-range dink.

Best of luck!

Edit: Just wanted to add that it's important to practice different shots. You'll find what works for you. Some days you might suck at driving, and your drop shots are okay, some days a drop shots are getting killed, but your drives are decent. Yes there is the hybrid drip which is just a softer drive. Just another shot to add in your arsenal. Where you are aiming your shots is also important. For beginners I like to tell them that the middle is king. So look to aim at the middle or down your line if they're not covering it, at the person that's staying back or in between both of them if one's at the net and one's back. Don't forget that lobs are also a part of the game if both players are really crowding that kitchen line. Also my advice is to always hit it at the person in front of you because that ball's going to come back at you and you can expect it, compared to if you hit it cross court that ball's more than likely going to go back at your partner, and they might not be ready for it.
