<prompt> Human: I 21 received two tax refund checks and I deposited both of them. Now the IRS is requesting one of the checks back but obviously I dont have it anymore. They say they will start collecting interest if they dont hear back in 30 days. Im a student and Im flat broke. What do I do?  <response>: Work out a payment plan and pay the interest. Consider it a lesson in spending money that isnt yours.
