@aurora4420 this can be a confusing topic, but let's simplify matters
here is the official IRS link that determines whwther someone is a dependent. Answer the questions as if you are your father. See what the answer is....
https://www.irs.gov/help/ita/whom-may-i-claim-as-a-dependent
Whomever your daughter lived with for more than 6 months is mostly who can claim her as a dependent. if that is you, then you can claim your daughter and your father needs to amend his tax return to remove your daughter. He will have to pay back any money he received (and that could be the Recovery Rebate Credit and the Child Tax Credit).
I don't understand the comment about your father receiving the dependent tax credit money. Other than, if you were unemployed in a year prior to 2021, you were not eligible for the child tax credit money as it required you to earn at least $1500 to be eligible for the credit, so maybe that is why the child was listed on your father's return (which would be tax fraud if the child was not truly his dependent).
However, in 2021, and that year only, that was not the case. You were eligible for the entire child tax credit ($3000 for children 6-17 years old) even if you did not work.
does that help?
