Form 3922 is an informational statement and would not be entered into the tax return. You will need the information reported on Form 3922 to determine stock basis in the year the stock is sold.
Per the Form 3922 IRS Instructions:
Instructions for Employees
You have received this form because (1) your employer (or its transfer agent) has recorded a first transfer of legal title of stock you acquired pursuant to your exercise of an option granted under an employee stock purchase plan, and (2) the exercise price was less that 100% of the value of the stock on the date shown in box 1 or was not fixed or determinable on that date.
No income is recognized when you exercise an option under an employee stock purchase plan. However, you must recognize (report) gain or loss on your tax return for the year in which you sell or otherwise dispose of the stock. Keep this form and use it to figure the gain or loss. For more information see IRS Pub. 525.
