Somehow my social security wasnot used with my pension making my income appear as if it were only the pension amount ,Now what do I do?

If you did enter your SSA-1099 when you prepared your tax return, it's quite possible it wasn't taxable.  A brief explanation of how it is calculated is provided below.

The social security benefits are entered, then half of the benefits are added to your other taxable income, such as your pension (and some exempt income if applicable) to determine if any amount of the social security is taxable.  If half of your benefits combined with your other taxable income is greater than the first threshold of $25,000 for single ($32,000 for married filing joint), then some of your social security benefits will be taxed. The amount of that combined total determine exactly how much of it is taxed, but never more than 85%.

TurboTax will do all the calculations and determine if any of your benefits are taxable.
