Last year my raven was taken to pay off student loans how can I find out in advance if they're planning to take this year's refund as well

If you are still behind on the loan it is likely your refund will be taken again. But you can check:

 NOTE: You can contact the IRS Treasury Offset Program Call Center at 1-800-304-3107 to ask if they have an offset for you on file. TurboTax would not have that information.
