Now find the create new field button in below right corner. 9. And give the name and display name. 10. Add the same button on your form with the help of drag and drop. Hope It'll help you..

you must have the "System customizer" and/or "System Administrator" role, If you do you can Click on the "Form Editor" when you have a contact open, you will be able to add new fields from their or you can edit the default solution navigate to the entities, then contact and under fields add one[You will still need to add it to the form for users to see it)
