After you file

You had to install the 2018 TurboTax program on the laptop using the CD so that you could work on the 2018 tax return using the TurboTax software.  

Unless you deleted the 2018 TurboTax program from the laptop for some unknown reason, the program and the tax data file are available on the laptop.  Print the tax return using the TurboTax 2018 software in the File section.
