As an active investor, be aware that your category Box A or Box D sales without adjustments do not require Form 8949, so there is no reason to import or key in those transactions.
Instead use the "enter a summary" option to put your numbers on Schedule D Line 1a or Line 8a.
Sometimes,
TurboTax takes note of this rule, and if the conditions are met, Form 8949 will not be attached to your return even when you do not use the summary option..
It is not good behavior.
