Why do owe taxes after entering my 1095-A?

Hi there,

  • I had got medical insurance through Covered CA with zero premiums in 20th Dec 2022 when I did not have income and qualified for it with zero premium.
  • (I also got medical coverage as IHSS Live-In provider for my grandma, but I did not include that W2 as that  had $0 wages in box1 as tax is 0 for live-in provider). 
  • I got a job in May 2023 and the coverage was not good. So, I continued and canceled it in Oct 2023.

I received 1095-A Health Insurance Market Place Statement

Under Part III, I see 321.90 in column A, 392.24 in Column B, 320.90 for each month from Jan to October.

When I enter those in TurboTax, it increased my Federal tax due from $2205 to $5191.

I am surprised as I thought Covered CA was free.

Please confirm if I am missing something. Thank you.
