If you have two W-2s with the same EIN that is resulting in your overpaying Social Security tax, then you will not be able to claim the excess amount on your tax return. Instead, you will need to file Form 843 separately to receive the refund of the overpayment.
You can still electronically file your return after adjusting your W-2 as explained in the TurboTax help article below. Take a look at the section for Single Employer and then the section for What if my employer can't or won't cooperate? The article also explains the procedure for filing Form 843 by mail after filing your return electronically.
