Source of auto-entry in Qualified Business Income Deduction Summary?

We have some Non-employee Compensation, reported on a 1099-NEC, which triggered the use of the Qualified Business Income Deduction worksheet and summary. On the Summary form (QBI Ded Summary), there is an entry on line 9, Total REIT dividends. We have, however, no REIT investments. When I right-click on the entry and then Data Source, it opens a pop-up that lists three types of Sch K-1 Worksheets (Partnerships, S Corporations, and Estates and Trusts) as the source. There are, however, no Sch K-1 Worksheets in in use in my return. I looked at my Carryover Wks, but found nothing there. I'm at a loss as to how to track this down.

Any idea what might be the source of this REIT Dividends entry or how I could track down the source of this one data point?
