How do I change the form layout from card to classic?

I followed these instructions: https://www.jotform.com/answers/1364792-How-do-I-remove-the-previous-next-from-questions

But I don't have the section "form layout"

You should do it in the Form Settings. Please follow the steps here https://www.jotform.com/help/493-How-to-Change-the-Form-Layout#How-Can-I-Change-the-Layout-from-Cards-to-Classic.
