How can I add another w-2 and 10-99 after already submitting my taxes? My state is currently pending but federal already approved.

You cannot make any changes right now.   You will have to wait until the returns have been fully processed and then amend.   You will need a Form 1040X which becomes available in mid- to late February.   Wait until both federal and state have been processed.  Then amend and add the additional documents.   Post back here for further help if you need it when you are ready to amend.  Do nothing now.  Do not try to change anything on those returns.

If you want to make changes, or add a document to a tax return that has already been submitted you should follow these guidelines.

• You must first wait until the initial return is completely processed.
• You will have to use the same TurboTax account that you used for the original tax return.
• Once you begin your amendment, you'll see your original return. 
  • The refund calculator will start new at $0 and only reflect the changes in the refund or tax due
  • Only make changes to the areas of your return that need amending.
• You have three years from the date you filed your return or two years after you paid the tax due (whichever is later) to file an amendment
