I am retired and received a W-2 from my former employer that only has an amount in box 12a, with the code DD, employer sponsored health insurance. Turbotax will not allow me to e-file because this W-2 has a value of 0 in box 1. Since the box 12a amount does not affect my taxes, can I just delete this W-2 in Turbotax so I can e-file?
