Thanks for the update @bobweissman Including the letter sounds like a good pre-emptive move; it's too bad there is no feedback loop from the IRS to find out what they actually do with a letter like that. I suppose if the only thing they do is scan it and file it, at least it will be there in the file at some future date when someone reviews everything, and if that helps reduce the potential for escalation into an examination then it would make it worth the effort.
