How did you pay double? And for what deductions? For Federal withholding? And you do not enter ssi on your tax return and ssi is not taxable. Do you mean regular SS Social Security or SSDI?
How do you know you paid double? The withholding is just an estimated amount.
Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
Married Filing Jointly: $32,000
Single or head of household: $25,000
Married Filing Separately: 0
Social Security is on 1040 line 5a and the taxable amount on 5b.
To see the Social Security Benefits Calculation Worksheet in Turbo Tax Online version you would have to save your return with all the worksheets to your computer. Or if you are using the Desktop program you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.
