Get your taxes done using TurboTax

@nexchap Your interpretation of my question is correct. When I go back to the original broker listing of the purchases I find that the K-1 Sales Schedule Breakout is close to the actual purchase amounts. The 1099-B purchase amounts are about 5% under the actual amount. Thus, I could use the K-1 Sales Schedule Breakout except that I found the first couple of purchases (out of approx 30 purchases) are either incorrect or missing when compared to broker buy records. I will therefore use actual purchase records to determine the correct purchase price and recalculate LT and ST Basis from there.
