I had the same problem with Schwab. I use TurboTax Home and Business running on Windows 7. After being on the help line for over an hour, these are the 3 things I did to resolve the problem. I list all three since I'm not sure which one fixed it.
1. Right click the Turbo Tax icon and select Properties. Go to the Compatibility tab and select "Run the program in compatibility mode for Windows 7".
2. In the Privilege Level on the same Compatibility tab select "Run this program as an administrator".
3. Uninstall TurboTax and re-install it with the compatibility selections above.
You may also need to deselect "Real time protection" in your firewall if you are using Microsoft Security Essentials. Also make sure your "3rd party access" is enabled at your broker if that is their requirement to import tax info.
Good luck.
