How do you transfer education benefits to a spouse when the service member has limited time left on their contract?

Please help!!!! My husband is attempting to transfer his education benefits to me; however, teb denied transfer because he doesn't have enough time left on his contract. He contacted his s1 about extending. S1 is saying that he needs the letter about transfer being denied. We did not receive one. He showed him on milconnect the denial. After reaching out to the army rep for teb per website he was told that he needed to fill a different form out but we can not find this form. I want to finish my RN and give back to my service members at the va hospital or base hospital but we need help getting the education to transfer. Any advice?????
