My 18-year-old filed her tax return without claiming herself as my dependent. She will file an amended return. When can I file as head of household on TurboTax?

Is there a specific sequence I need to follow (e.g., her amended return is accepted on TurboTax and then I can still file hoh before April 15th? I want to resolve this asap without losing money. She lived with me and I supported her for over 6 months in 2023.
