Do I need to file a new form 1120 along with 1120x when amending previously filed return?

I am amending a previously filed form 1120. The instructions for 1120x do not say to file an updated 1120 as well but turbotax auto populates an updated form 1120 & prints it as one of the forms required for filing. Do i need to send in an updated 1120 along with form 1120x
