I need the 2017 tax return for Jo Ann Jennings. My sister is paying for a copy of this return for me as I have no credit cards. I need help in getting the 2017 return.

I need a copy of my 2017 tax return. My sister is paying this expense, however, it shows the 2018 return, not the 2017. I do not want to pay for the 2018 as I have it. please advise.
