Why am I being charged the shared responsibility payment in 2019? there's no penalty after 2018. I was denied marketplace ins & didnt qualify for medicaid. Is it an error

Under the Tax Cuts and Jobs Act, the amount of the individual shared responsibility payment is reduced to zero for months beginning after December 31, 2018.  Beginning in Tax Year 2019, Form 1040 will not have the “full-year health care coverage or exempt” box and Form 8965, Health Coverage Exemptions, will no longer be used.  See Individual Shared Responsibility Provision
