Are you claiming a qualified dependent? (Your qualified dependent for HOH filing status cannot be a GF or BF or their child.)
Am I Head of Household?
If you qualify as Head of Household, when you enter your marital status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.
Change your filling status on the Personal profile screen.
Review the TurboTax articles Guide to Filing Taxes as Head of Household and Filing Taxes as the Head of Household for more information.
If your qualifying person doesn't live with you refer to the TurboTax Help article Does a dependent for 2024 have to live with me?
