So here's a list I made for someone coming from a d20 System (D&D 3.x, Star Wars d20, d20 Modern, Pathfinder, Starfinder, etc...) to Traveller. It has the Traveller skill, then below it has the d20 skill designated by " - ". It's a work in progress, but it's something you can give a new Player.
Let me know if you think I should change any of it.
