Yep, go to roll20.net/ and make an account. Once that's done, go to "Find a Group" (it's really easy to find) and tick the box that says "new players welcome" since even if you've played before, you'll need to learn how the website works. You'll be able to filter the games that show for which version of D&D you want to play too, which I'd definitely recommend doing

Incidentally, I have a friend named polly who is a troll and generally has her name with a "z" in it in her usernames. I didn't see your name until I was nearly done typing this comment and now I'm mildly freaking out
