Can I save my turbotax online files on an external hard drive, instead of a computer, now that the program is online? Much prefer CD version...

The TurboTax desktop editions for tax year 2024 are available for purchase and downloading to a personal computer - https://turbotax.intuit.com/personal-taxes/cd-download/

If you want a CD for the software it is available after you have purchased the download and have the license code on this website - https://turbotax.intuit.com/lp/ttd/4021/

are you aware the "CD version" still exists you can download TT software and use it as you did before
