Where else can I get my employer's EIN beside payroll and didn't work for the same employer?

That information will be on your W-2----which the employer has until January 31 to issue.   TurboTax cannot get the EIN for you.

  W-2’s come from employers.  There is not a federal or national website that provides W-2’s.   If your employer is partnered with TurboTax to allow the W-2 data to be imported into the software you can do that---but you need the actual W-2 so that you can enter the EIN and the amount from box 1 to import the other data from the W-2---which just saves you the little bit of keying in of the other information.

W-2's come from your employer, and they have until January 31 to issue it.  Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it. Some employers have payroll sites that will have your W-2. You might need to phone, text, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.

Your employer's EIN will be on your current and past W-2s.   You might want to try using the Auto-Import function.  For tax-exempt organizations, you can find the EIN using the IRS Tax Exempt Organization Search tool.
