You should have also received a regular K-1 for the Federal filing. Put those into TT first. Then when you're ready to do Oregon, you can note the differences between the K-1 and the OR K-1 in the Other Adds code 119 (for partnerships or S-Corps) or Other Subs code 323 (for partnerships or S-Corps) in Forms mode. There may be some other codes that apply such as in the 15x and 35x range. The StepbyStep mode doesn't show all the possible codes. If there are no differences on the OR K-1, then you can ignore this.
The lack of TT support for OR K-1s is a shortcoming. TT CA State has a place in StepbyStep for CA K-1s, but the OR State module doesn't doesn't acknowledge them.
I don't have experience with the OR-21 K-1 so I defer to these documents
