When I enter ssa1099 my refund goes down-why?

[Texas Roger]

Up to 85% of social security benefits can be taxable depending on how much other income you have. They are not taxable if 1/2 of social security plus other income is not more than $25,000 ($32,000 if MFJ). If your benefits are taxable because of other income, your refund will go down when you enter them.
