You can't get 2018 from Turbotax....that isn't supported anymore.
You'd need to get the forms as PDF files from the IRS website...print them out and fill them in manually....then mail them in. Same thing if you need the state forms.

AND...don't try to buy the 2018 software on a 3rd party website either. Even if you do find an available CD...that is just a very preliminary set of forms that needs to be, but cannot be updated anymore....and all the forms are labeled Do Not File. Many of the needed tax laws for 2018 aren't even implemented on the CD, thus requiring software updates that can no longer be obtained.
