Avy - The API client and the B/A client are independent of each other: you cannot use the B/A client to operate on data files backed up by the API (as used by TDPs, and as reported by your query). Some B/A queries return results on API data, but that's about it.
Whereas this seems to be Oracle backup data, I think you'd want to follow the "Removing old backups" instructions in the TDP Oracle manual. Richard Sims
