if you are an active investor you should be aware that Box A and Box D transactions with no adjustments do not have to be itemized on Form 8949. Thus there is no reason to import those transactions.
instead report subtotals on schedule d Line 1a for A and Line 8a for D
If you have wash sales, it gets more complicated since those have to be itemized on Form 8949 and the summary totals adjusted accordingly.
enter the wash sales on Form 8949, then use the subtotals on the bottom of that form to know how much to subtract. Be sure to NOT check the adjustments box in the summary window.
