Why is my Federal 1040 printing at end of Ohio tax return

When I go to print off my paper returns to mail in (For both Federal and state) It prints my federal return first, then the Ohio State return  prints, but at the end of the Ohio Return 2 pages of the Federal 1040 also print out again. Are you suppose to send the 2 pages of your Federal 1040 with your Ohio tax return when you mail them?
