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 payroll clerk. 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?

Keep everything in writing and save the confirmation numbers. It saved me later.

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
