no, only teams forms are premium, Microsoft forms are free.
check my second suggetion, your licenses may not have allocated.
1) Click your profile icon, click view account fo to subscription. there under your licenses see if power automate for office 365, sharepoint forms are listed or
2)go to microsoft 365 admin center (if you are a admin, or power platform admin) -> active users -> select one and see the licenses and apps. In apps see all the required ones are checked, forms, power automate, sharepoint, power apps etc. if not tell admins to activate them. otherwise all the users using your flow will get the same message as yours now, prompting a free trail.
please mark as the solution if that works
