Divorced in 2025. Want to file as single, but I have two adult dependents in college.

I was divorced in December 2025. I have three children:

  • 19 - in college full time
  • 20 - in college full time
  • 16 - 50/50 custody with my ex.

My ex is taking the tax credit for my youngest, who is a minor. We agreed that I could then claim the two older children, which would give me a $500 credit for each ($1,000 total). She is also taking the "head of household" filing status, which I believe means I must file as single. Is this correct? 

 

If I must file as single (because ex is filing HOH), how do I change my filing status to single? Turbotax won't let me!!!

I go into "My Info" and there is no place where I can change filing status. It asks If I am divorced, I said yes. Then it auto-selected head of household. I didn't have a choice and can't change it.
