Multi User of TurboTax Download

I'm using the downloaded version of TurboTax Deluxe for my 2024 taxes. Can my son also download it to his computer to do his taxes? Ideally it would be his return, filed with his unique information, email address etc.  Is this possible or allowed? Would I need to file my taxes first then sign out to allow him to download?  I don't know if this approach will cause issues.

Thanks,

Gary
