Thanks.
I entered 0 as a cost basis because I would need to individually calculate each week's cost basis using the ETF provided table and some required math. It was just not worth it for the $ involved.
My post here describes the situation better, with a picture of the 8949:

The proceeds are rounded to 0, so I have line after line of 0 proceed, 0 cost basis in the 8949. The rounding error adds up and doesn't come close to matching what is reported by my broker's 1099-B.
