Husband is an optometrist/optometry professor. He taught a class at a convention. They pd him by check and we received a 1099misc. Turbotax put that information onto a schdC. It wants to know the business code (I'm guessing 61100 or 999999?), the accounting method for his business (cash or other?) and if he materially participated. He doesn't have a business. He has taught a class at this convention before, but I don't remember answering some of these questions before and we've always received and filed a 1099misc. I researched materially participated...it doesn't look like yes or no. I'm so confused! Thank you so much for your time!
