As an active investor, be aware that your category Box A 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.
Same for Box D which goes on Schedule D Line 8a.
If you have wash sales, it gets more complicated since those adjusted transactions have to be itemized on Form 8949 and the summary totals adjusted accordingly.
Enter the wash sales on Form 8949, then use the subtotal results on the bottom of that form to know how much to subtract. Be sure to NOT check the adjustments box in the summary window.
