If the 1099-K reports online sales, and ALL the sales sold at a loss (or had no gain) which is a weird way of saying that none of the sales made a profit, don't adjust on that screen, select "personal sales" for the type of income, and then select "All items were sold at a loss or had no gain."
That should be the end of it if ALL the items did not make a profit.
If EVEN ONE item sold at a profit, you would select the other option "I sold some items at a loss or no gain" (which is a weird way of saying "at least one item sold for a profit") and enter the amount of the sales that DID NOT make a profit.
Next, you would enter the sale or sales that did make a profit in the investments section.
