Thank you very much for the detailed response and the how to aspect of it..
The reason I think the 529s could do it is because when I make a withdrawal they asked me to specify what sort of withdrawal it is and have around eight choices. They could have a choice that addresses the type of withdrawal were discussing.
Of course that's only useful if the IRS made changes to the format of the 1099-Q.
So they do know, in the sense that they asked me. For example they do ask the qualified withdrawal, a non-qualified withdrawal etc. but that info doesn't show up on the 1099 q.
Regardless, I really appreciate the detail.
