How do I enter schedule K-1 Box 11A (estate beneficiary deduction) data into form 1040 line 24k?

Line 11A represents Section 67(e) expenses and you can enter that figure on the appropriate line in the K-1 section.

Be sure to select Estates or Trusts (Form 1041) and note that you may have to upgrade to Premier if you are using the online version of Deluxe.
