Add an Edition?

I am hoping there’s a way to add an edition of a book. Currently, for the book I want to add to my list, there’s only the audiobook version listed. I have tried adding the paperback book with the Goodreads link as normal, but it hasn’t “linked up” as another edition of the same book, nor does it come up as a new book entirely.

I want the physical book edition for my TBR list.

Any hints?
