Something is not gelling here. Your question indicates you are using Self-Employed Edition, which is way above PLUS. Is that correct? If so, all of your upgrade choices will be grayed out, since Self-Employed Edition is the highest upgrade.
What are you trying to do? Are you trying to unlock a 2017 return? Is the locked 2017 return in the SAME account as the 2018 return?
Have you already filed your 2018 return, or is it still in preparation?
Did you use Self-Employed Edition to prepare and file your 2018 return, or did you try to upgrade a 2018 Free Edition return and upgraded too far to Self-Employed Edition? Or do you need Self-Employed Edition because you have a Schedule C business in your return?
We can tell you what all to do once your situation becomes clear.
