On my 1098T for Grad School, the Box1 amt. is for "Payments received for qualified tuition". The $ I paid in tuition by my reckoning is different from Box 1 #. Help?

You claim the tuition credit, or report scholarship income, based on your own financial records, not the 1098-T. In the 1098-T screen, click on the link "What if this is not what I paid the school" underneath box 1. You will then be able to enter the actual amounts paid.
