There won't be a place to indicate that some of the wages were from workers compensation. Workers compensation is NEVER reported on your tax return, as it is usually disbursed after-tax. So, since your employer paid you the way that they did, and included it as income on your w-2, they SHOULD have already paid taxes on that income and that should reflect in your withholding amounts shown on your w-2.
If you believe that for some reason your employer did not include these amounts properly on your w2, you should contact your employer. Otherwise, enter your w2 information into TurboTax exactly as it appears on your w2, and you are done!
