Early Termination Fees

Hello, how does someone determine their early termination fees? 

For context, I have tried the solutions from older posts:

• 2 years ago - look up contract under terms and conditions. Didn't exist.
• 6 months ago - direct messaging on this forum. Link no longer works.

I also tried talking to the AI agent, who was not helpful because they couldn't answer hypothetical questions....  I don't want to go ahead and cancel until I know all the context!

How can I check this?
