It will not let me type anything in the boxes in the 1099-DIV section

If you are unable to enter anything into a field it is possible that the page you are trying to enter your information on did not fully load. You can Refresh the page in your browser to reload it and retry adding your information. If you are using your numeric keypad to input information, make sure your "Num Lock" key is on. If neither thing solves your problem, consider some other things you can try:

1. Exit TurboTax Online (Save & Sign-Out), then close and reopen your browser and login again
2. Try a different browser: Chrome or Firefox (IE 11 is currently not working well with the software)

If none of these things resolve your problem, you can also contact TurboTax Customer Support. Contact Customer Support
