If your refund was offset and your TurboTax fees were supposed to be deducted from your refund, you will receive an email from TurboTax with instructions on how to pay your fees directly. You should receive this email approximately 36 days after your expected refund date. There is no way to set up an official payment plan for the fees, so I recommend you just make payments towards your fees as you are able if you are unable to pay the full balance at this time.
You can check out the TurboTax FAQ below for more information regarding this scenario. Please feel free to comment below if you have additional questions.
