After you file

If you didn't file your return you can revisit the Investment Income section and make the changes:

1. Log in to your account.
2. Go to Federal Taxes.
3. Go to Wages and Income.
4. Scroll down to Investment Income and click show more.
5. Select Stocks, Mutual Funds, Bonds, Other and click Revisit.
6. Select Review next to the Brokerage statement that you need to Edit. 

If you already filed, you need to amend to make any changes.

Here's how you amend your return:

1. Sign in to your account.
2. Scroll down to Your tax return & documents , select 2019 and then Amend (change) return. 
3. Select Amend using TurboTax Online.
4. Follow the instructions, your refund or tax due will change to 0. This is normal on amended returns.

Amended return can't be e-file, you need to print it and mail it in.
