I am in BC and I am trying to file my 2018 taxes Getting Error 513 and everything looks good. So why am I getting this message?? I want to submit.

I have entered the tution and number of part time months on the Federal Slips input.  It is showing up correctly on Schedule 11 and BC S11.   When I look at the error report I go through each item and there is nothing wrong.    How do I fix this?
