Steering column & turn signal help

[yimmy149]

My turn signals stopped canceling themselves after making turns a couple weeks ago.

I took off the steering wheel today to take a look, and found some plastic bits floating around the steering column. I'm attaching photos of the parts, and the control stalk assembly in case someone can help me identify where they are from and what I need to replace.

I forgot to put anything in the photo for scale, but the larger piece of plastic is similar in size to a US dime.
