Turbotax has no way of knowing that a tax return has inaccurate info. perhaps your spouse filed by mail to avoid the IRS computers from quickly catching the w-2 misstatements. Innocent spouse relief may be available but you need a tax pro to review your situation. If you do nothing, the IRS can go after your bank accounts, put liens on your assets, garnish your wages, etc. They can do the same to your spouse or both.
see IRS PUB 971 for info on this relief
