I am claiming my brother on my tax return. He received the 3rd stimulus last year and I received my own since we filed independently. For 2021, he is not filing taxes as he was unemployed. I am claiming him as an "other relative dependent". When I filed, i selected that i only recieved $1400 as that is what matches the paperwork sent by the IRS. Now the $1400 is applied to my refund. Is this correct? What should be done?
