Hi Mike:

We were getting the same diagnostic on a 1065 and resolved it.  The state of CO doesn't want the DR 0107 filed every year, so as long as you've filed it previously, if you go to screen 32.1 Partner Misc Info.  Select the out of state partner, then select Colorado Information under the Sections tab at the lower L.  Under the main screen, under Colorado Information, put a 2 under Form DR 0107 (form on file with agency).
