If the amount you received was less than what your grandson's tax return stated he would be receiving (after TurboTax fees), there are two things that could have happened. Unfortunately, there's no way of knowing exactly why it was adjusted right now, but in either scenario, you will receive a letter within a few weeks with an explanation. There will also be a number that you call to get further information from them.
1.) They made changes to your tax return. If they changed something which altered the amount of your refund, you will receive a letter from them within the next few weeks with an explanation as to why this change was made.
2.) It was determined that there was a balance owed somewhere else and your refund was partially taken to pay the amount owed. In this case, you will also receive a letter that contains detailed information of what this offset was for as well as contact information for the agency that received the payment.
