After you file

Where do you see that it is not taxable?  Look at line 6a and 6b on your form 1040.  The full amount should be listed on line 6a while 85% should be listed on line 6b.  

TurboTax is calculating it properly when I enter it.  Double check where you entered it if you are not seeing the numbers on line 6a and 6b.

Social security should be entered by selecting the following:

1. Income
2. Retirement Plans and Social Security
3. Social Security
4. Enter the full amount in Box 5 Net Benefits
