Thanks for your help, but I don't seem to be able to find this option on TurboTax online.
When I click to report a stock sale, it takes me on the next page to a screen which says "Which bank or brokerage sent you a 1099-B for these sales?" I don't see any option for anything like "No 1099-B was issued" or similar. I don't know how to get past this page, and I'm now stuck :(
