How can I keep someone from filing under my son's social security number? He is 18 & I claim him on my taxes. His identity was stolen during Equifax breach.

He is a full-time college student, does not have a job. I was able to file Form 14039 Identity Theft Affidavit for myself, but since he is not a minor, it would not let me file one for him.

You can't keep someone else from filing and using your son's SSN.  You should just file your return in the normal manner, claiming your son.  If the IRS receives two returns, each claiming the same SSN, their computers will reject the second return they receive.  If that happens to you, just resubmit your return by printing and mailing it, and the IRS will request further information, and they will determine who has the rightful claim.
