Have you located the 2017 return, and is it in the SAME account as what you are using for 2018? And when you try to download/print, does it ask you to pay?
If all you want is the 2017 AGI, there should be a free link in that same section of "Your Tax Returns & Documents". Under 2017, look for "View adjusted gross income (AGI." Does that work? If you need the complete 2017 return, we can tell you how to get it.
You appear to be in Self-Employed Edition, which is way above PLUS. Self-Employed Edition is 119.99 for a Federal return, while PLUS is 19.99. Do you not intend to use Self-Employed Edition?
If you only want PLUS, do you intend to prepare your return in Free Edition? Free Edition is only for very simple returns, and many people have to upgrade to a paid edition.
We can tell you how you can downgrade to Free Edition, then upgrade to PLUS if that's what you want. Or if you do intend to use Self-Employed Edition, we can tell you how to pay for it in advance. That should unlock all prior returns in the SAME account.
