After you file

because of the CARES Act, they will not garnish the refund for any delinquent student debt.  Also, there are no student loan payments due for the next 6 months (through Sept 30).  Because you filed, you are automatically in the queue for the Rebates (assuming you are not a dependent of someone else)

 

it may be it's not on your student loan account because they stopped garnishing on March 27 (the day the CARES act was signed)
