I suggest you edit your W-2 entry to see if that box is checked. It could also have been checked in a previous year for an employer that you no longer have. In that case, you may need to delete a previous year W-2 file that you aren't using in the current year as follows:

2. Choose Tools
3. Choose the Delete a form option under Other Helpful links
4. Find the errant W-2 in the list and delete it
