I already filed my tax returns but later on receive an additional (different)w-2 form-from same job in the mail? Can I cancel the current filed return or can I just add?

I have tried to "amend" but I am unable to at the moment.  The system says I must wait.  Will I receive a penalty because I have filed too quickly?

You will not receive a penalty for filing too quickly - although you may owe the IRS money if your original refund was too large, and if you don't correct your return and pay before April 15, they will charge a penalty for late payment.  You cannot cancel a filed return - it can only be corrected by amending.  

If your return is accepted, you will only be able to correct your return by amending.  You can do this in TurboTax after your return has been processed by the IRS and you have received your refund, if any.  A link to the instructions for amending in TurboTax is below.

If your return is rejected, you can make any necessary corrections before resubmitting your return.
