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 (Line 2) to know how much to subtract which gives you the Schedule D line 1a totals (or 8a totals). Be sure to NOT check the adjustments box in the summary window.
Line 1a and 8a are only for aggregations with no adjustments.
you can combine as many broker accounts as necessary as long as the conditions are met.
Line 1b and 8b would apply as well to items you did choose to detail on a Form 8949 even if there were no adjustments.
Line 1a/b and 8a/b are only for Box A and D respectively.
If you sell a house you don't get a 1099-B for that.
