Solved
I purchased 2020 Premier with a disc, but I must use the program online instead. Ultimately I'll need to use TurboTax through a Chrome browser.
Thank you very much. I suspected that but needed to confirm. I'll be fine now.
FYI: During the interim I borrowed my wife's old iMac desktop and am installing the disk app there. When I purchased CD package I didn't think ahead to realize my iPad has no CD drive and no USB port for my remote drive. That's why I was trying to use the online application.
