Hi and welcome. Working two stitches together after a yo will create a hole (eyelet) which will be the buttonhole. To keep in pattern I would yo, k2tog and continue in pattern. When you come back to the yo after turning the work purl it. If you had a knit and purl to work together, then it would be a p2tog to keep in pattern.
ETA Oops! I should have said, as salmonmac did, to knit into the yo on the next row.
Denial, anger, bargaining, depression, acceptance...the five stages of frogging.
