Earned $7,000 from DoorDash, but didn't record expenses.

Hi

My son worked doing DoorDash in 2020, earned $7K, however did not record expenses. Since he's 19 and a fulltime student he'll need to file the 8615 and used my tax rate. Can he still create the Schedule C without entering expenses? I just want the income to be considered earned income in order to boost his standard deduction.

Thanks!!
