In the drop-down list for Sales section, select "Short-term basis not reported to IRS (noncovered)" or "Long-term basis not reported to IRS (noncovered)" as appropriate.
If you want to enter individual sales instead of totals, when TurboTax asks how you want to enter your sales, select "One by one" instead of "Sales section totals." The drop-down list for Sales section is the same.
