Filing taxes for foreign limited company

I'm curious about my particular situation. I moved to the UK in the end of 2021 and started a limited company in the UK in October, but I did not start trading (receiving any money) for that limited company until 2022. I filed in 2021 for my foreign limited company to be considered a disregarded entity. Just curious if I need to do anything for this on my 2021 taxes given that my UK limited company was formed but did not receive any money in 2021. Otherwise I just have a standard W-2 for the first half of 2021.

Thank you!
