Composer and lyricist are displayed under "Written by" on Spotify and will appear when you click on “Show Contributors” for the appropriate track. The producer entered by you is listed under "Produced by". You can enter this under "Track List" > "Edit" > “Additional Information” > “Further Collaborators".
