I believe you stated 2021 tax return, not 2022. Only the 2022 can be filed electronically with Turbo Tax. Firms that prepare the prior-year return can file it electronically, just not self-prepared returns.
As to your 1098-T and 529 information, there is a $500 difference. You note that your son's room and board is less that college's published expectations. Those kids eat a lot of food and I wouldn't be surprised if he met those numbers! Either way, you can use the numbers the college published instead of your own.
This may remove the extra $500 so that it all evens out. Then the 1099-Q is just tucked into a tax folder and it does not need to be entered. If not, the student claims $500 income on his return. Unless, you can claim the AOTC college credit and choose to claim it.
Whoever claims the student , claims the 1098-T and college credit. If your income allows you to claim the college credit, you would be better to say that $4,000 of it went to your son. Then, he would claim that income on his return. If you can't claim the credit, there is no need to add income to his return.
Please see another post of mine here for more details of the 529 exceeding college expenses. Also, see Pub 970 for more information on the AOTC credit. For 2022, the income phaseout is $80,000-$90,000 or for MFJ $160,000-$180,000.
@Hal_Al is correct as always and using the $4,000 for college credit which normally yields a much better tax return.
