Yup, that looks like the problem. Did you use the Step-by-Step process for entering his info? If so you can go back through it again.
You can take a short-cut by clicking on the large "Federal Taxes" tab, then the "Deductions and Credits" tab below that. Look through the numbers in the 2024 column to make sure they look correct.
At the bottom, you can click "Continue". TurboTax will then review your entries, do some math, and decide that you should be using the "Federal Standard Deduction".
Do Not check the box to "Change my deduction". Then hit Continue.
Disclaimers: I use Premier, so these steps may be slightly different for you. I haven't checked to see if there are different rules for Earned/Unearned Income, but I can't see how anyone with total earnings under a few thousand would owe any taxes, unless he is a dependent child.
