While the 8919 doesn't have the address, you can only use the code H (it looks like) if you received a W2 AND a 1099-MISC/1099-NEC.  So, that means that the address is going to be on one of those.

So, I was wondering if the Code H somehow went through an automated under-reporting type system.  Would be fairly easy for the IRS to pull those (if they had the resources to do the programming).
