Reject IND-510-02 means, the Spouse SSN in the return has been used as the Primary SSN on another return filed for the same tax year.
It's possible you have been a victim of identity theft, if your wife didn't file a return on her own.
Unfortunately your only option will be to paper file your return. I would also suggest you Complete IRS Form 14039, Identity Theft Affidavit and mail it along with your return.
