I had Medicaid healthcare only I didn’t receive a 1095-a but got the 1095-b . Do I continue to file normally. Or do i NEED 1095-a

Since you had Medicaid for the whole year, you won't and shouldn't get a 1095-A form. You don't have enter form 1095-B. Keep it for your records. 

• Medicaid counts as health insurance for the Affordable Care Act. In the TurboTax Healthcare section, just answer that you had health insurance all year.
