Change to 1 blog page

Hey all!

I am struggling to come up with a good solution here.

On my most recent blog post I want to include a form fill for users to fill out in order to view a .pdf (gated content).

How would I add the form to just 1 blog post? Anytime I try to make edits, I am making the edits on the template itself and the form shows up on every previous blog post.
