Well, as the table above shows, 20H2 reaches end of life on May 10 this year. If you got to Settings > Update & Security and click 'check for updates' then you should be offered the optional feature update to 21H2.
For any 2004, 20H2 or 21H1 system this is not a major upgrade (unlike upgrading your 1909 system). All versions from 2004 up share a common set of system files. Provided they are fully up to date with the latest cumulative update then they already contain the 21H2 features, but in a dormant state. These features are turned on by installing a small (165k) Enablement Package, which installs quickly like a cumulative update.
If you haven't been offered 21H2 by the end of May, then you could download and install the Enablement Package yourself.
