The problem is that the IRS expects each transaction looked at in case any of the transactions were losses due to personal use, such as lunch at Starbucks or payments towards bills, etc.
One option is to do this outside of TurboTax and only enter the total lines for short term and long term transactions that do qualify to be reported. Please see the TurboTax FAQ: How do I enter a large number of stock transactions in TurboTax Online?

ok so it might just be easier to do this manually and look at the FAQs you attached?
Yes, that way you don't have to edit all of the transactions. You'll have to delete the imported information because you won't be able to E-file with errors. To edit or delete what you imported, see How do I update or delete something I imported into TurboTax? Then follow my instructions to enter your transactions using "summary".
