In my experience, you won't see the QTC exam info in MyHealtheVet. At least, I never saw mine there, and it was in Spring of 2015.
I also clicked that button, but my made no difference in getting results. Emailing Sec. McDonald and UnderSec Hickey at the 15 month point is what generated movement on mine.
I agree with Gastone. Read a book, find a hobby, just put your mind elsewhere, because the claims process can drive you nuts.
