I erased an entire section of my form by mistake. How can I get it back?

I was trying to update the prices in my form but was not able to. I thought I could delete the one price item only, but it deleted the entire section. 

I need to retrieve the form with the entire pricing section. Also, I need to know how to make changes to the pricing without losing the entire section. Thk You
