Please be aware that the new tax law changed the look of the 2018 Form 1040, it is supposed to be two half pages--front and back--but when you print it out, both sides print on one page. The signature place is on "page 1" of the 2018 Form 1040, right after dependents are listed.
On the 2019 Form 1040, the signature place is back at the bottom of page 2.
