I completed my 1099's, printed and pressed submit. I have 1099 's for my contractors. I can see that I have efiled for federal. But It also printed out Copy 1 for North Carolina. I did not make any withholding for North Carolina. I see that another post say.... that reads file if required. What is required? What does this mean? As I did no withholding do I trash these. Or will they be filed with no tax withheld?
