Debit card I don’t own appears on Apple ID payment method

Recently I tried downloading a free app when I was then prompted to update payment methods for an expired card. I was confused because it was a Visa card I wasn’t familiar with. I tried to remove the card but it didn’t work. I was told there is a subscription that is being paid for with that card. I am in a family plan, however there’s no shared subscriptions between us. However my only two subscriptions that I own are attached to my actual debit card. Very confused why I’m being told I have a subscription with this random card. It’s preventing me from downloading any apps.
