For box 16, do I enter it once or twice when having a second row of information?

If you're entering state information on a W-2, you do not enter it twice.

Some people work in more than one state that has income tax; that's why there's more than one line.  It comes up when you hit Enter or Tab.

One entry is all that's needed.

If you are asking about something else, please post back to this thread.

W2 has second line on 17, 19, 20, only 1 line 15, 16. Do I add a line, duplicate info in 15&16 or leave them blank on the second line?
