IRS Tax Refund Query by sugar1973: Can I try out to get a tax refund again even even though I just filed them last week? I just recevied a tax kind right now which allows a student loan interest deduction for my taxes. I did not know I was going to get this. I currently filed my taxes last week. Can I add this details to increased my refund or is it as well late? I am so clueless when it comes to filing taxes. Thanks.
