I think in general I agree with your analysis.  The glimmer of hope may lie in Section 1341 but I think it's really going to come down to a legal question on the "repayment".  The dollar amounts are substantial enough that I'd recommend the client get a legal opinion on this based on the language written into the court order.  If she had actually repaid the $60K that might be a stronger argument for a 1341 claim but it sounds like the 2019 benefits were reduced rather than the 2018 benefits repaid.
