After a nightly drop test went from 19.5 to only 19I'm done shocking. After sitting in the sun all day, it's down to 13.5 FC. The target for my CYA is 5. What level is safe to go in?

You should try to keep all of your chemistry questions together in one place. I don't know what your CYA level is now, without hunting around through several other topics you have started, so I can't really answer your question about when it is safe to swim.

With CYA at 40, it is safe to swim up to 15, as long as nothing is going wrong.
