How to turn off textbox sample?

I can't seem to figure out how to turn off textbox sample on my forms.  I do not want the fields to have the sample text in them.

The form has no textbox sample on my end. It is probably because of the autofill function of your form.

Anyway, you're the only one seeing this. Your client/users including me will only see empty fields when we open the form.

Also, enabling autofill in the form is to allow the form to save the entered text in your browser local storage. It will always pre-populate the form if the user uses the same browser until they submit the form.
