Try browsing dnd discord servers on Disboard. That’s how I did it.

Roll20 had tons of games last I checked, both D&D (several different editions) and dozens of other ttrpgs. Has a lot of great features such as a robust “find a game” system, built in dice roller, unlimited free character sheets and more. Literally can’t recommend it enough!

There are a ton of Facebook groups too for finding online games. Although most use discord rather than zoom/Google meet. I run games on Discord using various vtts such as foundry and tabletop simulator. There’s a lot to pick from.
