OK. I will give you all the steps below.
Also be aware there's a free option if a tax return transcript would suit your purpose. You may be able to immediately download a 2017 return transcript at the IRS website at the link below if you qualify to open an IRS account there. If you don't qualify to open a free IRS account there, you can order one to come by postal mail, which normally takes 5-10 calendar days.
