You can't access the program or your 2018 return? Did you download and install the 2018 program? Did you download your tax return as a .tax2018 File?
After you get the program installed the first thing to do before you open your tax return .tax file is to update the program and install any state programs you had. Then open your file. So you first might need to start a fake return to be able to download the state program (go to FILE - NEW).
