Worksheet for Determining Support - Misc expenses

I really appreciate all the I have received so far!

 

I just want to figure out if the follow that my son pays for out of his own money are considered support and to include them on Line 2 and Line 18?

- Car insurance

- Cell phone bill

- Misc personal spending that my son spends out of his personal bank account

   - snacks, tag renewal, entertainment, and small purchases for things for his room
