I just now did my taxes and notice I had forgotten one 1099R How do I go back and add it. Haven't sent it in yet?

The best way to get back into your return is to:

1. Sign into your Turbo Tax account

2. Click on tax home or take me to my return

3. Scroll down till you see Your tax returns and documents

4. Click on your 2018 return, and then select add a state (you are not actually adding a state, this just prompts the correct menu)

5. Navigate to where you need to on the return
