You mention that you are separated from your husband but you do not mention how long you have been separated. If you are still legally married, you cannot file as "Single"---your filing choices are married filing jointly or married filing separately.....OR if you have been separated for at least the last six months of 2025 and you are supporting the dependent child, you may be able to file as Head of Household.
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.
