Look at your lease statement and it should tell you the remaining payments. Then check your residual. Then add those numbers up. Then check the value of your Tesla. If you are indeed underwater (very likely especially on a newer lease), then there’s nothing you can do other than take a big hit if you turn the car in early.
You could also go to Leasetrader and see if someone wants to take over your lease, assuming that’s allowed in your lease contract.
