You do not report his income on your tax return.  He can file his own tax return and if you are claiming him as a dependent he is required to select on his return that Someone can claim you as a dependent

Would it affect me if he gets anything or if he has to pay

No.  A tax refund received or taxes owed by a dependent have no affect whatsoever on your tax return or on your tax refund.

No it won't affect you.  But how old is he and is he a full time student?  If he made over 4,700 you might not be able to claim him.  

Be sure on their return they check the box that says they can be claimed on someone else’s return. If their only income is W2 and under 13,850 they do not have to file a return except to get back any withholding taken out.

You do not report his/her income on your return. If it has to be reported, at all, it goes on his own return. If your dependent child is under age 19 (or under 24 if a full time student), he or she must file a tax return for 2023 if he had any of the following:

1.          Total income (wages, salaries, taxable scholarship etc.) of more than $12,950 (2022) ($13,850 2023).
2.          Unearned income (interest, dividends, capital gains, unemployment, taxable portion of 529 distribution) of more than $1150 (2022) ($1250 2023)
3.          Unearned income over $400  and gross income of more than $1150 (2022) $1250 (2023)
4.          Household employee income (e.g. baby sitting, lawn mowing) over $2600 ($13,850 if under age 18)
5.          Other self employment income over $432, including money on a form 1099-NEC

Even if he had less, he is allowed to file if he needs to get back income tax withholding. He cannot get back social security or Medicare tax withholding.

In TurboTax, he indicates that somebody else can claim him as a dependent, at the personal information section.
