It's likely there will be no tax liability since social security is your only income. In that case you would receive no benefit by using your mortgage interest and property taxes.
The social security income is used in combination with your other income to make that determination. Income such as interest from savings, dividends, capital gains/losses, etc.
If the first threshold of $25,000 for single ($32,000 for married filing joint), is met then some of your social security benefits will be taxed. The amount of other income plus half of your social security benefits are combined to 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. The filing requirement chart is attached for you to review if you choose.
