Very Stuck on Collar Stand and Collar

I am doing this shirt as my first ever button-down and am having trouble with the collar. My collar stand is significantly longer than the shirt neckline, and I also feel that the shirt neckline is going to be quite tight if it buttons at all. (I need it to button I will be wearing a bow tie with it). I am wondering if I did the front placket right. I did view A and cut the required inch off the front panel piece then adding the front placket for A. Was I not supposed to cut that front piece or----? I am doing the sew along on the blog as well as the actual instructions but I am so lost. Thanks so much to anyone who can help me.
