I need to enter an adjusted cost basis from a K-1 from a Partnership ETF I received. I can't get to the right screen from the "Stocks, Mutual Funds..." section.

I am amending my return because I received a K-1 from an investment into USO. Whenever I click the Edit/Add button for this section, it takes me to the investment sales section and when I click Edit for the brokerage entry, it takes me right to the sales entries. This doesn't see like the right place to enter the adjusted cost basis from the K-1 sales schedule. I tried canceling the amendment to start over but it remembers all the info when I try to amend it again.
