If you filed, it is like dropping it into a mailbox - you cannot get it back.
You'll have wait until your return is either accepted or rejected.
- If rejected, you can make any necessary changes.
- If accepted, you'll need to amend your return.
- To avoid unnecessary delays, do not amend until your original return has been fully processed. You will need to print and mail the amendment.
- Allow 8-12 weeks for processing.
See this TurboTax FAQ for help with amending.
You can check the status of your amended return here, but allow 3 weeks after filing for it to show up.

Just to be clear. The first answer by C-rose3217 was wrong. You can NOT enter it next year. You have to report all your income on the same year tax return. So if your return was accepted without it you need to mail in the Amended 1040X return to add the missing info and correct it.
