I have recently been playing a lot of online chess and have around a 2000 rating in rapid on Lichess (I realize the ratings are not the most accurate, but it is my only point of reference). I'm wondering if there would be any good OTB tournaments that I could participate in at this level, and if there are specific websites that would be the best to find good local tournaments.
There still aren't as many OTB tournaments as there were in 2019, but they're starting to come back. You can find USCF rated tournaments at this link. Just make sure to set the "Online" option to "No" if you only want OTB tournaments, and then you can search by date range and either state or proximity. Bear in mind that that for these tournaments you'll need to pay for a USCF membership on top of the entry fee, if you don't already have one.
I'd also suggest asking at a local club about other tournaments in your area which may not be USCF rated. There may not be a centralized place where these are listed; they may rely on word of mouth.
You don't need any particular rating to participate in most tournaments, but I realize it's no fun to go out there and lose every game. Rest assured that with that sort of online rating it is unlikely that you will do so; your rating is likely to be higher than the average player's.
