If I understand your dilemma, you don't know how to have the yarn in position for the first stitch after you turn when it's a knit. I would move the yarn into position to do a knit stitch before I slip one. I think that would solve that problem. Changing the stitch count might end up causing more confusion later on in the pattern. When you start it again be sure to ask any questions. Eventually things can get sorted out. Maybe I'll be able to start mine soon and will better understand what you're dealing with. HTH
I should never overestimate my basic arithmetic skills.
