How can I update my business country from Portugal to the United States, please?

I have verified the new US address, but it's only showing up as a residential option, not as a business information option.

For context: I currently live in Portugal and created an account with my personal address, but I now own a US-based LLC and want to use it for my Amazon business. I have updated my tax interview accordingly, but I still can't update my Legal Entity country.

Thank you!
