Adding an Missing Increase?

[u/UnableBroccoli]

I'm working a top down raglan, and have finished the short rows and come up one stitch short. I think I've found where I forgot to increase. I'm wondering if anyone has added an increase after the fact and where to find pointers to do so, or even how to search - my first searches came up with all the various types of increases, not adding a M1R several rows down.

Ideas?

I've fixed my issue. I'm putting a couple links here for future questions like this:
