The second W-2 seems proper to me to indicate amounts deferred in a prior year have now vested and become subject to Social Security and Medicare taxes. In such a case the amount in box 1 is unrelated to the amount in box 11. Make sure that when entering this W-2 into TurboTax that you indicate that the box 11 amount does not represent a distribution.
If TurboTax still complains. it's probably the case that the two Forms W-2 would normally be summed together and issued by the employer as a single Form W-2 and that's what TurboTax expects to see.
