After you file

Is this answer still correct in 2024, when filing 2023 taxes? 

 

I filed for an LLC as of 12.21.23 with the intent of launching 2024. $0 income and $0 expenses. I still work my main 9 to 5 job and already filed both my federal and state taxes based on my W2 income. I just learned that the requirement to file taxes for a single member LLC would be to attached a schedule C along with my personal taxes that I had already filed.
