I have a 1 year old Apple M2 MacBookPro Sonoma 14.3.1. I cannot upload previous itunes libraries to this computer, as it says my computer is not authorized, and I have to go to the itunes account to authorize my computer, but there is no option to do so.

There appears to be a bug with the current incarnation of Music when it comes to the deauthorization commands.
On your Mac you can try System Settings > Click on your Apple ID > Click on Media & Purchases > Under Account click on the Manage button. There you may see the Deauthorize All button.
Otherwise can you access a copy of iTunes, or Music on a different build of macOS? From there you should be able to reset your authorizations and start over. Alternatively reach out to Official Apple Support and ask for their help to reset your authorizations.
See also Authorization vs. association - Apple Community for further background.
