Knitting flat on circs?

I’m a little confused. I have a quarter of my stitches on a stitch holder and need to finish by knitting the rest flat on my circular needles but my working yarn is attached to my stitch holder. Did I do something wrong? Shouldn’t the working yarn be attached to the first stitch I’m going to knit like on straight needles? Please help. I’m quite the newbie to all this. TIA!!

The yarn’s attached to the last [B]stitch[/B] on your holder, but that should be next to the stitches on the left needle, which ought to be what you knit next, so just start knitting.

thanks for the help!!
