Quick question (I hope) before scheduling a session. Added a new CD to
my Music library yesterday, and when I tried to add “album artwork) was
told I’d have to log into iMusic Store before that could happen. Tried that
and nada. I know that’s not an “end of times” problem, but just wondering
if Apple is no longer providing that or what? Anyhow stay well and hopefully
soon I can schedule an onsite session?

Apple does require you be logged in to your AppleID in order for it to try to retrieve artwork within "Music" (formally known as iTunes). It has been my experience that you have to request artwork several times over the course of an extended period of time. And even then, I have seen updates dissolve the cover art. In other words, you might wake up one day and see the cover art you had for certain items, no longer exists. This happens mostly with TV shows and movies however.

There are suggested steps one can take to update album art work that requires removing music then re adding, signing out of Apple Music or iCloud music library, and other steps. These are not ideal. Short answer, I don't have a great answer on how to acquire missing album art.

In the meantime, here are a couple other suggestions that may help.
