Do you have your tax file ending in .tax2019?   If you don't have the CD you probably don't have the License Code for it either? Don't think you can download it if you originally installed from the CD.   You might have to buy it again here,

Then After you get the program installed the first thing to do before you open your tax return 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 TAX RETURN)

Then go to FILE -Open and find your return.
