I know nothing about coding I am retired from my previous occupation. and a veteran looking to learn.
Well, we teach web dev here. If that interests you, I would start there, at the beginning.
Definitely start at the beginning of the Free Code Camp course and work your way slowly through the lessons. It’s a great starting point and the concepts can be used in a large variety of coding paths. If you follow them in order, they really build upon each lesson and you’ll be up and running quickly!
