For original songs, you can put (Original) or (Original with ProducerName) after the name translation and before the date such as on Himawari's page:

"Sora ni Tsuku" (Arrive at the Sky) (Original with ) (2010.04.15)

No. 29 as you mentioned is fine. That section isn't only for cover projects, it's for any singing activities the utaite is involved with.
