Get your taxes done using TurboTax

It may be. Sometimes the IRS will catch your missing W-2 and send you a letter letting you know about the missing information and they will correct it for you or if you have other issues on your return they may reject it.  So, in the meantime, you will need to wait to see if it is processed or not. 

If rejected, you will simply need to fix whatever error caused it to be rejected, then add your W2 and then resubmit your return.

If accepted, once your return is processed you will need to follow these instructions to Amend Your Return once the 1040X is available in Turbo Tax. You will see your refund/amount due set back to $0, you will then be able to enter your W2. Your amended return must be paper filed.  When you get to the end, it may "appear" that you can e-file it, but it must be mailed.  It will take 10-14 weeks for the IRS to process your amended return.  Once submitted you can check the status of your amended return here Where's My Amended Return
