What I'm thinking:
Your working yarn is on your right needle. The provisional stitches are on the left needle. You can then knit 3 stitches onto the right needle before turning.
Half as clear as mud? I fear that if I were looking at it, it wouldn't make sense to me at all. I'm undoubtedly missing something and had better bow out before I make things that much worse.
You will get it worked out!
You can't knit the left sock first. Ever.
