Chill, it will come when it wants to.

This OP says the car has already said "connect to wifi to download update". Thats quite a bit different than others asking about getting the update their car has not been flagged for yet.
OP, here are a couple things you can try:
1a. Try forgetting the wifi connection to your network in the car, and re connect.
1b. Ensure that you are connecting to your wifi on the 2.4ghz connection, not the 5 ghz one. Your car will connect to both, but I have had issues trying to get updates on 5ghz while 2.4 works fine.
2. Ensure you have a good connection where you are parking. 1 bar isnt enough for example. Your car can show a connection, but it is possible its not a good one. Run a speed test while connected using the car browser if your browser is active in your car.
3. Once you have done both the above, try to reboot the car by holding both steering wheel buttons till you see the screen go black. Re start the car by stepping on the brake.
4. Try shutting the car down fully using the "power off" setting on the screen. Once you power it off, let sit for at least 15 minutes (30 minutes would be better) to allow the car to fully go to sleep. Come back after that time, then start the car again.
If none of the above work, then I would schedule an appointment using the app, use software update as the type. This is not normally a productive thing to do if the car is not prompting you to update already, but once it has prompted you, like yours has, sometimes the update is corrupt and needs to be re pushed by tesla.
