NEA source mishap, how can I sort this out?

All the work in my NEA is my own except for ONE of the quotes I used which I did ask chatgtp for. It provided me a source for the quote and I put it in, but upon further reflection, the quote doesn’t actually appear in the source. Will I get in trouble for this? Could I quickly change this so it all gets sorted? I already handed my work to my teacher.

why would you trust chatgpt to be reliable about anything?
