The modding tools should be located in the installation folder. Those are Editor, ArtManager, QuestEditor, PSEditor, etc.

The documentation on those aren't as high as one would wish, but there is a few tutorials and starting guides. I suggest you look here : https://titanquest.fandom.com/wiki/Modding_Main_Page
