I already filed my tax return and receive the money but I want to add my child to my return and I also received another W-2 form I want to add to my return is it too late

No, it is not too late, but you will have to file an amended tax return.

The amended return will allow you to include both you child and the new W-2.

It is a carbon copy of your original, but it brings your taxes back down to zero. (You got your refund, so you're starting all over again.)

The amended return will calculate any changes you make on your return.

 

To enter your child, go to My Info and add them.

Post the W-2 to Wages & Income

 

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
