How do I amend?

 I am on SSDI.  My daughter due to Covid didn't make more than half my income 2020. So when I filed my taxes I got confused and in  the recovery rebate worksheet I put what my daughter got, the $1200 and the $600 with a zero balance on line 30. My daughter hasn't filed her 2020 yet. On march 17 she received $2800. A couple days  later I received $1400. I know it was my return. But I do deserve a stimulus as she didn't  make enough this year to claim me. Since she hasn't filed her 2020 yet, how do I correct this? I knew it was a mistake as soon as I filed but I couldn't amend in TT until the 25th so I want to get this right.

I don't know why I filed this way chalk it up to Covid brain. I have been on SSDI for many years and never needed to file.
