On Form K-1 for Item M, the IRS instructions state...
"If you have contributed property with a built-in gain or loss during the tax year, the partnership will check the “Yes” box. Also, the partnership will attach a statement showing the property contributed, the date of the contribution, and the amount of any built-in gain or loss. "
Is there a specific format for the statement? Or do I just make an excel sheet showing the information they're requesting, and attach it as a PDF to my return?
