The software is creating multiple 1099-B forms with 6 transactions on 1 and 23 on another. Also, 3 transaction that need to be on 1099-B are not included. Help!

My consolidated year end summary from my brokerage frim has 32 transactions that are applicable to 1099-B. The TurboTax software created a 1099-B for 6 of these, another 1099-B for 23 of them and left out 3. Any idea why this is happening?
