My daughter is 17 which didn't qualify for the child tax credit. I filed my return early. If Biden changes the child tax credit to include 17 year olds, can I ammend?

I just filed yesterday through turbotax. I know the IRS isn't accepting returns yet, but soon.
If Biden's plan to increase the qualifying age to include 17 year old, will I be able to amend my return so that I can claim the updated credit?
