How do I access my clipboard on iPhone 7?

So I copied a terribly long text that contained very important words that needed to be said.

However, while writing it I kept getting distracted so I copied it and commenced to respond to incoming texts- among other things.

I had to copy an address and paste it into my maps search bar for directions and now I can’t figure out how to paste the long text I wrote so I can finish it.

Did I lose it when I copied the address?
