Side button baby sweater

I’m knitting a baby sweater, left side is only 22 sts.wide. Right side is 74 sts. after shaping neck on the right side and putting on the neck and front sts. The left side is longer then the right sts. There is no neck shaping on the left side. I took out the right side, I thought I didn’t make it the right length, but the it was right. The right side is 8 1/2 and the left side is 10 inches. How can I correct this?
