E-file reject IND-517-01 usually happens when you claim a dependent, but that person has filed a tax return and didn’t indicate that someone else can claim them as a dependent.
This error cannot be fixed. Your return will have to be mailed. Use a tracking service.
the dependent, probably the first listed, will need to amend their return AFTER it is fully processed. Ask each dependent to see their return to make sure it's just one of them.
Amended return are taking the IRS 5 months or longer to review.
