In Desktop Turbotax Premier 2024, I've entered my 1099-K Summary but cannot find where to itemize each sold item and cost basis. I'm not prompted and can't find where.

None of the help in Windows Turbotax Premier 2024 - or online search - helps me navigate Desktop Turbotax to locate how and where exactly I need to go to itemize my 1099-K personal sales and I need to enter cost basis, fees, shipping etc. for each item. Even the Federal Tax check finds no errors in my taxes, even though I only have a 1099-K summary entered.
