The TMDB Id is an Id that can be used on TMDB.

If you want to search for the show on other databases, you need to use the title on the Id of it on that database, not the TMDB Id.

Thanks for the reply, but the databases that I use are not online. I use Collectorz Movies. It has a place to input the tmdb id number to search for series info. No problem though, I will hand enter the info.

Each database has its own ID criteria.
The TMDb ID is not the same as the IMDB ID.
In your example of The Sopranos:
TMDb ID 1398
https://www.themoviedb.org/tv/1398-the-sopranos
IMDB ID tt0141842
https://www.imdb.com/pt/title/tt0141842/reference/

I think Collectorz Movies may use the IMDB ID.
