Get your taxes done using TurboTax

I work and live in Brooklyn NY. On my W2 in Box 20, I have NY SDI. TurboTax says that is an error.

Box: 18: 260.00
                947.47
Box 19: 1.30
               20.98
Box 20: NY SDI
               NEW YORK CITY

How do I move forward with TurboTax?

Thanks,

Dan
