You can enter just about anything you like for the EIN. Since there is no tax withholding, the details of the Form 1099-R are not transmitted with the e-filed tax return. The Form 1099-R is entered into TurboTax only to get the earnings to appear on Form 1040 line 4b and on Form 5329 Part I. If you don't feel comfortable entering a made-up EIN you can always leave that entry blank and print and mail your tax return.
