How to verify immunization records?

What is the best way to verify my immunization records with a doctor if I cannot see my PCP until after the due date? I tried to ask an urgent care if they would, where I went to receive my TB tests, and they said they were unwilling to do it.

I’m just unsure if I should email my PCP and send them the form? Do I try to schedule an e-visit? It’s just a paper they have to fill out confirming I have the all the vaccines from childhood.

Advice on how others did this would be greatly appreciated. TIA!
