Qualifying for surviving spouse status

[lunacat]

My husband past away in 2023, the filing status I used for 2023 is Married filing Joint.  For 2024 tax, I filed under Qualifying Surviving Spouse.  I have a child who is in graduate school full time, he is 25 years old and has income over 6K.  He lived with me all of 2025.   I will not claim him as a dependent.  However, when I run TurboTax, it thinks that I can still use the Qualifying Surviving Spouse status through my son.  Is this correct?  Turbo tax knows his age and he is not disabled.  From what I understand, I should file Single. Am I right?

TurboTax is correct.
