Health coverage after losing my job: marketplace or Medicaid?

I have 16 weeks left on my current insurance and I am comparing options. I have read a lot of threads here and could not find my exact situation. I think my income this year might qualify for a subsidy. Is there help filling out the forms?

Losing job-based coverage usually opens a special enrolment window, so check the deadline on the official marketplace site. I missed it by a day once and regretted it.
