My total income is incorrect by over $3000.00. How do I change this?

Is it over $3000 or under $3000? 

There could be several reasons for this problem: 

1) Please make sure none of the income information is not duplicated, if this is the case you can delete the duplicate one using these steps 

1. Open your return in TurboTax. (To do this, sign in to TurboTax, and select Take me to my return.)
2. In the left-side menu, select Tax Tools > Tools.
3. In the pop-up window Tool Center, choose Delete a form.
4. Select Delete next to the form/schedule/worksheet in the list and follow the onscreen instructions.

2) If it is under $3000 you can enter the information on your input screen. 

3) You can also verify all the information entered on your W-2, 1099s and other income related documents.
