Education

I have similar circumstance: We, I (parents) file MFJ and daughter in college, with W2 small income so she wants to file separate return. We paid part of her tuition with 529. Most posts I am seeing says to enter 1099-Q on her return, but 1098-T on parent return.  I entered 1099-Q on her return, then turbotax posted large federal tax. It wanted me to enter 1099-T. I want to take the tax credit so I'm not sure how to do that.
