Schwab 1099 Import unsuccessful

I have two Schwab 1099s and I was able to import the smaller one successfully. The larger one gives me a message saying "The import was unsuccessful check your connection..." I am using TurboTax desktop and since one works this isn't a connectivity issue. It is something unique to the larger 1099. I have done research and there are not more than 10.000 transactions only a few hundred. Can someone please help other than doing it manually???
