Deductions & credits

This was helpful. I'm now stuck on what to enter for Schedule D however. Do I type in the same amount as the 1099-K gross income, or do I type in the net loss I incurred selling the items? When I type in the net loss, TurboTax redirects me to "Fix" it again, and sends me back to the Schedule D line (which is auto-entered as "Untitled." Very much appreciate the help with what do enter for Schedule D.
