Entered an updated W2c as my company mis-reported income. Increase is around $800, but Turbotax is saying $9,500 due in tax. The $800 equates to $242 in additional tax.

The estimate on the header correctly shows the additional tax due @ $242 Fed, $47 State, but the body shows $9,752 for Fed and $47 for state.

Check these items:

• If you are doing an amended return, you must enter any amounts already paid or refunds received. 
• You should only have the w2c as income. The original w2 should not be on the return.
