No, I've never heard of a single piece of evidence that's turned up.
You'll hear people speculate--and speculation is all it is--that Jesus was being trained in this or that or several schools of various types, everything from the Essenes to the Hindus to the Egyptian mysteries. TBH, that sounds about right to me, but then again for all I know he was taken up in a flying saucer and educated by the Anunnaki on a space station. You never want to let speculation cut you off from discovering the truth.
On the flip side, and I think these are very important points, all those long crucial missing years speak strongly to two things:
(1) That the New Testament was not made up out of nothing. Why would anyone make up a story with the whole middle of it missing? And anyone that claims the NT is fake never brings up their own explanation for this.
(2) Those years really were important and have been purposely hidden from us. The NT has all this carefully chronicled information about his childhood, then all this carefully chronicled information about his final three years. You'd think someone would have written a short book saying, "Then this guy just took off one day with sandals and a backpack, off to the south is all anyone knows, and then he never even wrote home." Nope, it's exactly like someone just cut the pages of the middle chapters out of a book.
Very interesting.
Are there any writings about what went on from 18-30?

Maybe they're in the Vatican archives!
