Client is amending a 2017 tax return.  her wage and income statement from IRS shows two 1099-Gs received - taxable refunds from two states (New Jersey and Illinois).

I have the last four of EIN for the states, but I can't seem to find a way to locate the full EIN.

Does anyone have advice on how to locate the EINs?  My client insists they never received the 1099-Gs...
