We can't tell you that. You likely need to call the credit bureaus. I think turbotax uses Transunion, but you should call all 3. Your file may be messed up, linked with someone else, or you may be a victim of identity theft. Hopefully only one file is messed up and the others are ok. You can also get free credit reports (if you can be verified) at https://www.annualcreditreport.com/index.action.
Each of the 3 credit bureaus now have their own online service for getting credit reports and scores, there is usually some level of free service but they will try and upsell you of course.
