I called United and told them Turkish can't see the update in their system. So, the United rep said they did something so that Turkish can see the update in their system.

I called Turkish about 30 minutes later and told them I changed the flight with United to Feb 2023 and that I need the ticket re-issued. The Turkish rep said he didn't see the Feb 2023 date in the system but he tried to re-issue the ticket for Feb 2023 anyway. He tried to price it out to see what I would have to pay and said I can't get the ticket re-issued to Feb 2023 because my ticket is only valid until Dec 31, 2022 (1 year after date of issuance).

It seems like I may be out of luck with this situation? Turkish won't re-issue the ticket because they don't see the update from United and also because of the ticket validity issue. I wonder if showing screenshots of my phone at the airport ticket counter would help at this point. It is odd that United Airlines even agreed to change my flight to Feb 2023 in the first place. Any ideas on what I can say to the ticket counter at the airport to maybe get this fixed?
