Knitting repair

I have a sweater that has a hole it in. I have done a regular stockinette stitch so far, but to connect together I’m not sure what to do. Can you help?

Where is the hole?

If you’ve worked stockinette to “patch” the hole but need to attach it to the row of knitting above or below I think Kitchener stitch is the answer.

I remember watching this video, there are others you can search for.
