We in the Community cannot see your screen nor your private tax data. Please concentrate on one issue and give us some data.
I can think of a number of reasons why you might enter a W-2 and not have any tax due or show a refund. But you have to give us a starting point.
"And, seems I owe over $1,000 for healthcare this year! " - Do you have health insurance through the Marketplace? And after you entered the 8962, you ended up owing the IRS? Again, we need detail.
"Also I can't choose "itemized deductions"" - you can normally choose Standard or Itemized, although there is usually not a good reason to second-guess TurboTax on this. Why do you want to Itemize?
