I used Turbo Tax For Business 2020 on my laptop to file an extension for my LLC. The extension did get accepted. Now I want to use the same tool to file my actual LLC taxes. How do I do that using the same tool. Do I select "Start a New Return" or "Continue a Tax Return" or Amend a Tax Return". I am confused. Please let me know what option do I select?
