I need to change my dependent status and say yes I can be claimed as a dependent. I already filed and said no. I’m not seeing the “my info” tab. How else can I change it?

If you already Efiled and your return was Accepted, you can't change your dependent status.

 

If your return is later Rejected, you can go back in and change it.  If it is Accepted and processed by the IRS, wait until you get your Refund and you can amend your return.
