Education

I filed an amended return for 2020 in February, it says it was completed last month in October. It was to claim the American opportunity tax credit which I had forgot to do. TurboTax showed that I would be owed 1000. I still had eligibility left as I had not completed 4 years of education and 4 years of the credit were not claimed. I haven’t received the refund and when I check my transcripts they say they were updated in October but the credit doesn’t show up. I haven’t been able to get the irs on the phone for months. Is this normal? What should I do?
