I believe that it is compatible with all recent versions of iTunes, including the current one (on the day of writing this, that's iTunes 12.12.9.4).
iTunes is used on all Windows PCs and on the older Mac OS Mojave (10:14) or earlier. If you have a newer Mac, using OS Catalina (10:15) or later, none of which have iTunes, use Finder instead.
So the first question is: do you have iTunes installed on a computer now? If so, connect the iPod to the computer and see whether iTunes recognises it. If it doesn't, have a look at this Apple article: If your computer doesn’t recognise your iPhone or iPad – Apple Support (UK)
If you are still having issues, post back here with detail about what happens when you connect the iPod to the computer.
