If you didn't receive a 1099-B, in the Investments section under Wages & Income, in TurboTax Online, choose 'Stocks' and continue as if you had a 1099-B.
Choose 'short-term' or 'long-term, did not receive 1099-B' whichever applies, under 'Sales Section' and 'Options' under 'type of investment'.
Save documentation for the Cost Basis/Sales Proceeds amounts you enter.
Here's more info on Investment Sales without 1099-B.
