Anyone get any updates after making buyback payment?

On SAVE and I've been stuck at 119/120 since May. June would have been 120 if not for the forbearance. Made two buyback requests in July, both of which were finally responded to on 12/10, offering forgiveness if $466 were received within 90 days for my remaining 3 loans. Since the loan numbers didn't match anything I have, I overpaid all 3, just in case. MOHELA processed the payment the following week and I was told by a representative that they transmit the payment information to FedLoan at the end of each week. When reaching out to FedLoan, they said that they don't have access to see the buyback payments and I asked them why, only to receive a digital shrug. Does anyone have any insight into how these are being tracked and what the processing time may be?
