Received Schedule K-1 after filing return. Do I need to amend return if no changes occur?

I had Turbo Tax take me through amending my Federal return, however, no changes occurred to my original return after I entered the Schedule K-1 information.  Is it necessary to file the amendment then?  Turbo Tax provided the 1040X amended return form and a complete copy of my Federal return.  There is a place for a reason for filing the amended return on the 1040x, which I put "I received a Schedule K-1 after I had already filed my taxes."  Would I have to attach anything else like the Schedule K-1 and/or the Federal Statement that came with it?
