did you already submit your tax return with just the first w2? if yes, you cant file your taxes multiple times. you should have waited until you had both w2s and filed them at the same time. you will need to make amend your taxes now, to include the second w2.
if you have NOT submitted your return yet, click on ‘income’ on the left hand side and choose ‘add another w2’
If you have filed your tax return and then discover that you have an additional W-2 to file you will have to wait until the IRS either accepts or rejects your tax return.
If the return is rejected you can add the new W-2 and refile your return.
If the return was accepted by the IRS then you will have to file an amended tax return using Form 1040X to add the W-2 to your tax return.
This link to the TurboTax Help page How to amend (change or correct) a return you already filed provides information on how to amend your tax return.
