2024 TurboTax No CD

Hello, TurboTax no longer offer CD version of the software for 2024?  I thought I saw a post that if I get the PC Window download version, there is a way to install the download software on a CD that I can reload later if I get a new computer?  Can someone help me on how to do this?

 

Also, if I get the PC download version with a key code, can I use the key code later to install the software on a different/new PC, or if somehow I delete the software on my current PC, can I reload it using the key code?
