Hi - I am claiming my son as my dependent and entered his 1098T in my return.  No American Opportunity Tax Credit taken.  TurboTax says my son has to report taxes on the leftover grants.  But you're saying that if a dependent has no income of any sort (earned and unearned), the leftover from grants is not taxable thus, my son does not need to file income tax.   Is this correct?
