Child has $800 unearned income of bank interest

[DatBio]

My child has bank interest of $800 (unearned) in 2022 and I included those interest as part of my overall interest as my income.

Q1: Since this is an unearned income for my child and it is less than $1250. Therefore, my child is not required to file a tax return. Is this right?

Q2: I want to amend my 2022 tax return to remove my child's interest portion from my own.  By doing so, we are not reporting my child's unearn income at all.  Is this correct to do so?

Thanks in advance!
