Get your taxes done using TurboTax

For 1099-B Noncovered Securities, do I need to enter them individually or can I summarize them?

One reason I am asking is because I summarized them and Turbotax had a note that said:  

"You're attaching a statement and have only Summary entries for this account".

Does that mean if I summarize the 1099-B Noncovered Securities, I will have to mail in the tax return (versus filing it online)?
