most software has an input for box 14
if its already included in box 1 then it shouldn't impact your return
looks at the back of the w-2 to see if it tells you what each abbreviation stands for, and if it gives you a place it should appear on the return.

My w-2 has an itemized balance at the very top showing how box 1, 3, 5 are calculated and it has the line item for the value as additional income. And in box 14 there's not code associated with either OCOMP or ESPP. So I think it's just informational: Here's a line from that link you posted, "Generally, the amount in Box 14 is for informational purposes only; however, some employers use Box 14 to report amounts that should be entered elsewhere on your return.". Thanks!
