If it's on any known leaked online database, you will find it on HIBP alongside when and where it originated:
Have I Been Pwned allows you to search across multiple data breaches to see if your email address or phone number has been compromised.
haveibeenpwned.com
HIBP reports my primary email (and the one I use on TPU) as uncompromised, though I did receive some funny spam the other day (by no means linked to TPU!) raving about how they had been stalking me for weeks and demanded 1.9 BTC or they would leak whatever filth I had been looking at online
I would not worry too much about it, mate. If anything to stay safe, I would run a malware scan and then look at migrating security from Microsoft Edge onto Bitwarden though. It's a lot more flexible, and slightly more secure than having it behind your Microsoft account, IMO.
KeePass and other offline vault solutions are unwieldy and of higher risk of data loss by accident, so I wouldn't recommend them when Bitwarden exists. Still, they might have their uses if your tin foil game is up there
