I filed taxes before receiving my 1098-T and entered my expenses manually. I also put in my school's EIN wrong. I claimed AOTC. I have my 1098-T now, should I amend it?

This is my first time filing taxes and I have not previously claimed the AOTC, but since other members of my family have the same experience and they are not receiving a refund, I'm feeling I did it wrong.
