If talking about Note 9, the official Android 10 firmware came out months ago. If your device is still on the beta firmware, go to the members app, select hamburger menu bars, then click on the gear (setting) icon and disenroll from the program. Once out of the program and phone connected to Wi-Fi, go to phone settings >software update> select Download and install to check for updates. You will not get any updates if your phone and SIM are not from the same carrier unless unlocked or from T-Mobile. Ensure you backup your data before the updates install. You'll get quite a few so be patient and have popcorn handy. Good luck.
