I sold multiple purchase lots from my ESPP. I entered the ESPP info and Turbotax calculated everything correctly for the first purchase lot. When I tried entering subsequent purchase lots, there are numerous errors (number of shares, cost basis, etc.). This appears to be a programming error - I successfully used Turbotax in previous years for ESPP sales. Something is wrong with the Turbotax Premier 2020 version. It sounds like numerous other people are having similar problems.
