Helping a friend with her taxes, and her 16 Y/O son receives $3,399 a year, as shown on the form. This payment is direct deposited into her bank account, to spend on him. She is head of household, and the boy is only claimed as a dependent on her tax return. How, where, and who is this SSA-1099 payment account for/filed? Does the boy have to file his own return? Thank you.
Edit: The boy has no other taxable income for the year.
