W-2 DOESN'T HAVE BOX D, AND TURBOTAX DOESN'T LET ME GO FURTHER EVEN I LEAVE IT BLANK OR PUT FAKE INFORMATION. HOW CAN I CONTINUE TO WORK?

In W-2 Box 'd' Control Number is missing. I can't enter any fake number or remain it empty - TurboTax doesn't allow me to go to the next page. What should I do?
