let's back up
1) why did the IRS adjust the return? why did your grand-daughter write a letter back (I assume she didn't agree with the adjustment). Can you explain what the adjustment was and why your granddaughter didn't agree? let's try to understand whether the IRS was right or your granddaughter was right.
2) have you looked at the transcript to determine if and when the refund occured?
