Actually I didn’t see any drop-down menu at the top of any screen (I am working in the “Apple universe”, if that makes a difference (?).), and the investment account downloads were all automatic. However, the answer I received reassured me that “short-term” and “long-term” gains are differentiated in TurboTax. So I finally found that by clicking on the “edit” symbol for a particular investment section, it would show all of the individual stock transactions, and whether short-term or long-term. Thanks!
