I live in Canada and had a son in 2019. We do not have a SSN, but turbotax requires this to complete our return. How can we overide this? We do not need child tax credit.

As mentioned above, my wife and I are US citizens, living in Canada. We have not yet been able to get him a SSN and it is now going to be difficult to get one for a while due to the border being closed (Covid 19). When trying to complete our tax return, Turbotax specifically says that we need to enter our child's SSN. This is a problem since we don't have one and are not sure when we will be able to get one. Can Turbotax manually override this and leave it blank? We do not need the child tax benefit this year, so it isn't an issue, I just want to be able to complete filing. What can we do? Can you legally file without mentioning your child was born? Will this cause issues next year when we enter a child that was born in a different year? Thank you for the help.
