Sorry---you are just not reading closely or carefully enough. Yes, he was 24. You yourself say that he had less than $4400 of income for 2022. That small income is the criteria that allows you to claim him as a dependent if you paid over half his support. You do not HAVE to claim him. You can remove his information from your tax return if you want to. Go to Personal Info and delete him if you do not think we know the tax law or that TT's software is not following the tax law.
Are you aware that many folks claim adult dependents who are over the age of 23-----like their girlfriends, boyfriends, parents, etc.? And they are able to do that because the adult they are claiming had less than $4400 of income, despite their age.
If you have a qualified dependent who is RELATED to you---like a son----you can 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.
