Is there a source that i can link to that shows all the words in the torah with a dagesh in the Samech ?
סּ is what you want.
Then go to https://mechon-mamre.org/i/t/t01.htm, for example (Genesis); use CTRL+F to search within the page, paste in סּ, including "match diacritics" (at least in Firefox), and you'll find 45 just in Genesis. (The first is 2:11, "haSovev").
Continue for the other books of Tanach, or use a script to speed it up.
