Health coverage after losing my job: marketplace or Medicaid?

My employer coverage ended at the end of the month and I am trying to work out what to do as a call-centre agent. It has been weighing on me all week. I think my income this year might qualify for a subsidy. Is there help filling out the forms?

A free navigator at a community health centre walked me through my options. It took an hour and saved me a lot of guessing.
