There was a discussion I was a part of that people say that make your dua from our Imams. I believe that we can ask through them but not from them and we can only ask our duas from Allah. So is my belief wrong?

Calling on the Imams directly, in the sense that you ask them to help you because they are alive (per 3:169) and have sustenance from God and you are asking them to share that sustenance with you, is permissible. Yes it’s not permissible to call on them independently of God, or believing that they are the creators of the universe or that they give people all their sustenance and God does nothing.
