After you file

On first reading I misunderstood you posts. (It was late).

 

If you already filed and were accepted, another person can still file on paper with the same dependents.

IRS will have to contact you and/or the other person to find out who is entitled to claim the dependents.

That will possibly delay both tax refunds.

 

Tell the other person that you already filed. that may deter them.
