Thank you @GeorgeM777 - very helpful. I delved into the forms a bit more and think I figured it out.
TT correctly uploaded all my cost basis numbers for all items and proceeds, as well as having the correct "total gain or loss" in the Investment section overview. Also, the wash sale loss disallowed was correctly uploaded.
However, it seems that when I click on the link to get to the Breakdown of capital losses, and ask it to show how it calculated this #, it reports net capital loss and net capital gains that are rounded versions of the #s entered in the investment section. I checked the math and think the rounding is the cause for the discrepancy - this net capital loss is the one that is reflected in other parts of my return (Eg state return).
From other parts of the TT help section, it seems that this sort of rounding is OK and standard in these cases...?
Thanks.
