Yes, leave off the dashes when entering the State Identification number in box 10b.
Which state ?
10b is your participant number assigned by your state. There is no mandatory IRS format, and 10b is not required for your IRS return. (However, leaving it blank may confuse Turbotax.). There is no requirement that it be any exact number of characters, so try entering it without the dashes, it should not matter if is it less than the maximum allowable length.
