What are you trying to find? If you were a W-2 employee then your employer's Employer Identification Number (EIN) would be in box b of your W-2. If you were self-employed then there is no EIN for you to find. You either use your own Social Security number or your Tax ID number (TIN) for your tax documents.
If you are trying to apply for unemployment compensation, you do that through your state's unemployment bureau. TurboTax cannot help with that. If there is something your state wants you to enter that you do not understand, you need to ask your state for answers.
