In reviewing the NYS return, TurboTax will not let me file electronically unless there is a number in box 12a on my 1099R. What next?

When TurboTax reviews my NYS return for retirement information, there is a box 12 that states 0.00.  However, TurboTax will not let me e-file without an amount in box 12a.  There is no box 12a on the 1099-R.
