I have an error code Reject Code IND-517-02. How do i know which dependent this refers to? How do I fix it?

[kpb1234]

Do I need to adjust something on the dependents return?

Did your dependent file a return?   Check if on their return the box is checked for Someone can claim   You  as a dependent  or if they claimed themselves.  

See this whole thread for reject code 517 and that getting a IP Pin might let you efile.
