Gmail email address weirdness

I know Gmail says if you created an account like something.something@gmail.com, it means you have all iterations of that like somethingsomething@gmail.com, but I do have one of these email addresses, and I'm seeing some weird stuff.

I have this email, and I basically use it as a secondary email, so I use it for Uber and some other things, and not my primary email that I correspond with people with.

About 3 years ago, I started getting emails from a church in Canada. It was a harmless discussion group of leaders in the church discussing outreach, and such. When I looked at the email they had for me, it was somethingsomething@gmail.com. I emailed the group back when I first got it and told them that I was not the person they intended to include, but they never responded, and I kept getting the emails, so I sort of just ignored it.
I then got an email from a hospital in Canada emailing information to what I assume was this same person, who apparently was giving out my email address. I unsubscribed from their email and let them know it was not my email address. Never got another from them.

Now yesterday, I get one of those google alerts that someone is using my email as a recovery email for another gmail account. It said if it wasn't me to ignore it,which I have.
Also yesterday, I got 4 emails from login.gov asking me to confirm my email address. I am ignoring those as well.

I look at my sent emails and such and it's only the ones I have sent out from this address. Should I check with Google or something? Should I just continue to ignore, or do something? I think it's reasonably impossible to talk to Google about gmail issues, but I want to make sure somehow my gmail address isn't in use by someone else.
