This grouping is for  the same stock throughout the year- "the groupings are for trades that are the  same legal entity". 

It will like save a bit of entry but not enough to make much of a difference if you have a couple of hundred different trades to enter.

I have been using the sold date of the latest sale when I group them - not technically correct but no other way to enter multiple trades in one company on one line

Hi, Thank you for your response. I understand the grouping of same stock under one entry. However, I understand that you can also report all of your trades for different stocks (>100 entries) under one entry. In this case, what information should be provided on the Turbotax?
