Health coverage after losing my job: marketplace or Medicaid? (Nashville)

My employer coverage ended at the end of the month and I am trying to work out what to do as an accounts payable clerk. 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?

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