You might try looking at the entry fields for the Form 2441...in my Lacerte software (an Intuit professional tax preparer-type software) that's where this entry goes...there is a general information screen for relatively unusual items like this...and that's where you make this entry...this should then show up on your Form 8821, page 2. Review closely! (I am doing this right now with an entry identical to yours which was included in AH on a Form K-1(1065).
