I purchased premier software . Imported 1099-B from robinhood but many of the sales are missing. I dont see an option to add additional sales only to edit

Your 1099-B imported data may have summarized sales, reporting in one entry.   Each sale does not have to necessarily be entered individually; summary totals for Short and Long term sales is acceptable. 

Type '1099b' in the Search window and 'Jump to 1099'.  At the Summary screen, click on Add More Sales (screenshot).
