knitting mistake

I started with 34 stitches and now have 35, I think I only messed up on the current row,but now I don’t know how to get rid of the extra stitch.
new Knitter needs help!!! Please

You can knit 2 stitches together and that one stitch is decreased. It will not hurt the item you are working on.

Yes, k2tog. Just make sure where you do so is in an area that won’t be a problem for pattern design.
