Another approach worked for me. After entering the ESPP lots in the step by step section, go to View > Forms and select the capital gains worksheet that pertains to the ESPP stock sale. In Part V Reinvested Dividends, enter the stock purchase lots for only the reinvestment transactions in the spreadsheet. The spreadsheet expands to the number of rows needed. TurboTax will include these lots in the final list of lots on the worksheet with "N/A" in the first column of the record. The total number of stocks will add up to the total sale properly (after all typos are fixed). Note that I could not find a step-by-step question in TurboTax to lead me to this worksheet. Probably most people figured it out themselves, which can explain why this answer wasn't found in this forum.
