I had insurance as well as my husband for all of 2018. It asks for a certificate number?? What is that? We had Blue Cross

If you both had insurance coverage for the entire year then that is what you should have indicated on the first screen of the Health Insurance section.  If you did not have any of the plans listed on the following screen, then you should have selected NO and continued.  This will have completed the Health Insurance section.
