I'm having trouble finding instructions on how to enter Section 751 gain that was reported on Partnership's Schedule K-1 line 20AB.  All I can find is that "751 gain or loss is recharacterization of gain or loss from the sale of Partnership Interest from Capital Income to Ordinary Income. If this isn't accounted for elsewhere on the K-1 or in its attachments, you may need to enter the disposition information on the Dispositions screen."  However, there are no instructions available (or that I can find) to input such information into the Dispositions screen.  

This is related to royalty type income from Oil and Gas operation.  If anyone knows how to get this entered, please let me know. Thank you!

Thank you in advance!
