Do not adjust the W-2s. Report them exactly as they are. You will not get a corrected W-2 from either employer because what each employer reported is what actually happened with that employer.
Because this is a Roth deferral (after-tax) you do not report the returned excess contribution as taxable income. So basically, once Turbotax says "you need to remove the excess", that's all that happens on your tax return. Nothing else needs to be changed or adjusted.
