What is a seam allowance?

Can Someone help me understand Butterick Pattern 4087(A) or just this sewing term?

So I am creating an apron with the Butterick vintage apron patterns. Its only five pieces minus the bias tape for edges. I have cut everything out and am now putting everything together. I am stuck at this sentence:

"Turn in seam allowance on unmarked edge of WAISTBAND 4 (piece 4); press.

What does this sentence mean?Does press mean iron? The drawing is really confusing because the waistband look backwards. Here is a finished picture of the apron:
