I focus on business returns for Amazon sellers. Sometimes I do personal returns because the amazon seller is a single-member LLC so I am completing schedule C. As a result, I end up completing returns that have capital gains and losses from trading activity. I have at least 2 returns where they have been day trading and have 20 page 1099-Bs. I am manually entering the information, but I assume there is a better way. Intuit Link doesn't appear to be able to import these so what I am missing. If manual entry in the only way, I underpriced the return big time.
