It's hard to tell what the issue is without knowing more about your return. More details would be needed to know for sure. Please feel free to add any details in the comment section.
Try to delete the offending worksheet with the understanding that you would have to start over on that worksheet. Especially if "it should be blank", this may be the best action:
- Open your return in TurboTax.
...
- In the upper right corner, click My
Account > Tools.
- In the pop-up window, select Delete a
form.
- Click Delete next to the
Schedule E Worksheet (or whatever is the problem worksheet) and follow the onscreen instructions.
