Are you trying to use a Turbotax account that your spouse used alone for a her business, maybe when she was single and you are recently married? When changing marital status you almost always should start over with a brand new Turbotax account, since some hidden details are very difficult to change.
Regardless of how it happened, you could maybe fix this by editing the SSN using Turbotax desktop. If not, you either need to completely delete the schedule C and start over, or maybe contact customer support.
