That's not what it means. Rather,

Reject Code R0000-544-02: The Primary Taxpayer SSN must not be the same as a Dependent SSN on another tax return.

This return has been rejected by the IRS because the taxpayer has been listed as a dependent on another tax return.

Verify the taxpayer's Social Security Number has been entered correctly.  If the taxpayer has been listed as a dependent on another tax return for the current tax year, no dependents can be claimed on this return.
