Have a college frshman with $1,449 in income, $3,214 in taxable scholarships and $755 in 1099-Q. Deduction shows up as $1,799. Trying to figure out why it is not $12,200.

Your standard deduction may be reduced if you are claimed as a dependent on another person's tax return. If you were another person's dependent during a Tax Year, your standard deduction will generally be limited to the greater of $1,100 or your earned income plus $350

In your situation your standard deduction is limited to $1449 + $350= $1799

something still isn't correct 

that taxable scholarship is considered earned income, so the standard deduction should be $1449+$350+$3214.
