Apple MAC and Elements 14, How do is save, copy or move the finished photo To a album or file or CD and out or Photoshop

I have an apple Mac newest software, Elements 14. I have finished with a number of photos and saved them....God only knows where... unlike my PC where they go back to the original Photo files/albums. I still have them on the edit screen and can find them in the photoshop library. I need to move them to my photo albums or at least be able to put them on USB drive or CD. I don't need them cluttering up Photoshop
