I was unaware P.S. had built-in the K-3 filing footnote.  I don't see where to create that.  Instead I create my own footnote for that.  But I do it as below:

(1)

Per IRS instructions, this entity qualifies.....

(2)

--- this I leave blank so the election out of the centralized ptshp audit regime prints below it.  The (1) and the (2) creates a better looking presentation of footnotes than the way P.S. does it.
