Hi Joan,
Welcome to the community.
A year or so ago, I found myself in a similar situation with my house insurance. I needed to contact them and couldn't remember who I was covered with.
The two simple ways I checked, I searched my emails for confirmation of my policy within the last 12 months.
Secondly, I checked my banking app/statement to see which insurance company I'd paid.
You may have a few insurance companies taking payments for cars, house, life etc. It can be useful to cross reference the companies with your emails to help narrow the search.
