Get your taxes done using TurboTax

when you use "TurboTax cloud" you likely mean online which requires you to log in to your online a/c and either finish it there (you would be using the online app not the version on your Dell) or upload the .tax2020 to the Dell and finish it there.  without a network connection to the Toshiba, you cannot access that file that's on it.  and no you could not have saved it to the cpu because that's not a storage device. if you want use your web browser to find out what a cpu is and does.  the file was saved to the laptop's hard drive.
