The amount to report from your SSA-1099 form, showing the worker's compensation, should be reported as it appears on your statement. In other words, enter box 5 - Total net benefits and medicare if applicable. (see image attached)
Do not enter amounts from box 3, which is descriptions showing the amount for each. Worker's compensation is not taxable, but sometimes shows up on the SSA-1099 because Social Security is repaying those amounts when the disability claim is resolved and finalized.
If you have amounts in box 3, that apply to earlier years, you may use a special "lump-sum" election to reduce the taxable amount. If you find none of your social security benefits are taxable then this will not apply. TurboTax will ask the questions, then optimize your return for the best results. (see image attached)
It is normal to have no federal tax withholding from your social security benefits. You can choose to have it withheld, but if you find you have no tax due, then you don't need to do that. If you decide you want to have some federal tax withheld from your social security benefits (either you or your husband or both) use this number to start the process.
