Zencart 1.5.8
php 8.1

I am working on setting up OPC with bootstrap ZCA template. I need to change the format of the guest checkout form.

When I do a guest checkout the form is as follows.
First name
Last Name
Country
State (need to remove drop down)
State/province etc…….

I can’t find the place to change the order of the forms,

Can someone assist me or lead me in the right direction. I feel like this is a silly question but I cant seem to locate where to make the changes
