"fill out form" in preview, bug sur

I have a lengthy PDF that needs a lot of things filled out and I'm having trouble with the ability to fill it out using preview.

I am aware of creating a text box and then placing it over the blank area of the document, but I thought there was an easier way. I feel like i used to be able to just start typing on the PDF and it filled it out. I've seen a "show form filler" from other posts but i dont see where that option is when my tool bar/markup is up and going.

any advice/help is appreciated.
