It sounds to me you might have filed a Form 1099-INT last year. In order to proceed without any errors, I would suggest you to remove the form from the program.
To delete the Form 1099-INT in the TurboTax Premier online version, here are the steps:
- Sign in to your account, select Pick up where you left off
- Select My Account (top of the screen)click on the drop-down arrow
- Select Tools
- Under Other helpful links, choose to Delete a form
- Select Delete next to the Form 1099-INT and Continue with My Return
