How do I add w2 and 1099 docs to my taxes that I already filed

If you have already filed:

You will have to wait to see if your return is Accepted by the IRS or Rejected.

1. Rejected: You can re-enter the return and add the W-2.
2. Accepted: You have to wait until you receive your refund (if you are getting one), OR any payment that you made toward your tax bill clears.   At that time you can amend your tax return.  Here is information about amending returns:  https://ttlc.intuit.com/community/amending/help/how-to-amend-change-or-correct-a-return-you-already-filed/00/25588
