Dropped Yarn Over! HELP!

I’m working on the Charlotte’s Web shawl and have dropped a yarn over and I CANNOT figure out how to fix the silly thing! I haven’t put in a lifeline yet (I know, I know) and have reached the point where I don’t really want to undo all those stitches because the possibility of compounding errors increases with every row. Is there a way to fix it?

If you know where the yo belongs, then you can just pick up the strand between the needles and knit into the front of it. It will create an eyelet like a yo.

If it’s traveled down, then I’m not so sure.:think:
