You will delete the W-2 next year. That is, after you start your return and the W-2 from the previous tax year is carried over to the current tax year, go to Federal->Wages & Income->Jobs(W-2) or do a Search for w-2 and click on the jump-to link, and delete the out-of-date W-2 (click on the garbage can icon).
The wording may not be exactly the same on next year's software, but you've got the idea.
