The $1,000 listed in box 14 on your W-2 form reports the income included in the line 1 amount that represents the discount on the stock you acquired. So, yes, the box 14 amount is added to your wage income and is included in line 1 on your W-2.
The cost basis of the stock would be what you paid for it plus the income reported on your W-2 form. What happens is you receive a stock worth, as an example, $3,000 but at a price of $2,000. So, the discount of $1,000 in this example is reported as ordinary income on your W-2 form. So, your basis is what you paid, $2,000 in this example, plus what you got taxed on from the W-2 amount in box 14 which was added to your income.
