Q.spring vegetable garden
I’ve been planting a veggie garden for years I alway till in the spring but the question is, is it really necessary to wait 2 weeks for the dirt to settle in the garden before planting?

Well, I'm not aware of the 2 week rule! That's one of the great things about gardening and gardener's, we learn from each other.
If your soil is worked, and warm enough, go ahead and start your garden!
