A W-2 form is a report from your employer to you and the IRS of your income.
A tax return is a form 1040+ attachments. You file one tax return that reports all your income and deductions for the entire year.
If you filed a tax return listing only some of your income, you must go back and amend that tax return to list all your income. That means going back into your online account, clicking amend under the list of things you can do, adding your other income, and then mailing the amended return along with a check for any extra tax you owe to the IRS. You must also amend any state tax returns.
With TurboTax online, each account can only file one tax return. If you tried to “file“ your second tax return by changing the numbers in your original account, then you will have a problem amending, Because your original account no longer matches what you actually filed and can’t be used as a base account for making the amended return. First, you have to put all the numbers in your account back to the way they were when you filed your first tax return, then, start the amend process and add any income that you left off the first time.
