When that notice came out I had two 2016 returns to amend, which I then set aside as less pressing than the current year returns.  I clicked on the link Lisa posted and my heart stopped.  I knew I had referenced the notice #, so I dug that out and it was hard to find.  Had to drill down at least 2x before I found it agian.  I am definitely hoping a notice trumps a frequently asked question posting.  When I prepare them I will reference the notice.  This is not the first time I have seen conflicting informaton posted on the IRS website, and probably won't be the last.
