I am growing Etrog (Ethrog) is yellow citron or citrus. I just started last year from seed growing! I don't see it in the plant database. I would like it add to my plant list. Could you tell me how! Or do it for me? I am new! I don't have an image.

I think what you are looking for is Citron (Citrus medica)

Hi I checked! Yes! My variety is Buddha'Hand (citrus medica variety Ethrog) It's not listed. I'm requesting in database.

It is already listed in the database. If you click on the link Jay gave you, you'll see that Citrus medica var. ethrog is a synonym for Citrus medica.
