Don't know why you couldn't transfer 2018 directly into the 2019 program. I have some ideas you could try if you still want. But it sounds like you got it into the online version.
You downloaded the .tax2019 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).
To continue in the desktop version see this…….
