Then you would need Form 8965 in your tax return, not Form 8962. Form 8965 calculates the penalty for the months that you were not insured. Form 8962 is only for those who qualify for Premium Tax Credits because they have insurance from a Health Insurance Marketplace and therefore receive a Form 1095-A. It seems to me that the IRS would only be asking for Form 8962 if they received a copy of Form 1095-A, which seems unlikely if you received a Form 1095-B (unless you should have received both because you changed to or from a marketplace plan).
