I had only one of those but I filed the superseding returns a few weeks ago with the community income split.  You're expecting IRS to provide 😅guidance😅 before May 17?  Even if they do, and it's negative, it's better to have a protective claim when they change their mind or are overruled.  But miracles can happen so maybe they will go ahead and encourage more paperwork.  They have only 1.7 million unprocessed returns left over from 2019, down from 2 million a month ago, and they say they can start the advanced child tax credit payments in July.
