As per @opus17 & @VolvoGirl you must enter all W-2’s on your tax return for the tax year to which they apply. Failure to do so will understate your income and affect your income tax due. The IRS will catch a missing w-2 and that could mean you will owe additional tax and penalties.
If you forgot to enter a W-2 and have not already filed your tax return, you can easily add the additional W-2 before filing your tax return.

If you have already filed your tax return, you will have to file an amended return for that tax year that the missing w-2 applies.
Here is a link that can help you with that.
