Hi friends, quick question

I took a dna test, 23andme about a month ago and got the results back. According to it I am about 46% Ashkenazi Jewish, which was quite surprising as I was just raised as your typical American white dude. The issue is I asked both my parents about this and they didn’t seem quite like they believed it, or skeptical. My first thought was maybe it was a mistake but those seem pretty uncommon. Is there anyone here with some tips to learn more about this heritage or someone who may have went through something similar? I’m interested in learning more about this , I never expected this, and to be honest used to be somewhat anti Semitic when I was in school in a “joking” way. Sorry if I’m ranting this just really shocked me lol, thanks!
