I thought SSDI was not taxable but when I enter the amounts it takes about $3500. away from my return. Am I supposed to enter her amounts or just leave it blank??

Social Security Retirement/Disability/Survivors benefits are reported on a form SSA-1099 and the benefits received are to be entered on a federal tax return. The benefits may be taxable depending on the amount of other income you have entered on your tax return.

Up to 85% of Social Security Retirement/Disability/Survivors benefits 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

Who is her?  If it is your wife then you enter the SSA-1099 .  You do not enter a dependent SSA-1099 on your return.

Sorry it can be taxable.

Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:
