No, it shouldn't cause a problem with filing or a delay - you can enter whatever limit the TurboTax program has identified as the maximum allowed. There are limits on how much employers can deduct for the types of taxes described in Box 14, but they won't affect your tax calculations.
Your employer has likely lumped 2 of the taxes (that apply to you) together on your W2. They are separate taxes with separate maximums, so you need to self-correct when you enter the W2.
This post describes the issue in additional detail, although the maximums were for another tax year (they are updated every year - But Turbotax tells me NJ SDI can't be greater than $67. What can I do?
