Health insurance; how have I to pay back the difference through my taxes? Do they automatic deduct through my taxes refund?

My actual concern is do I have to do anything at all when I see this message "How much of the difference you have to pay back through your taxes = $105" in the Health Insurance tab, like cut a check of $015 that I own and send to IRS / CoverCalifornia. Or TurboTax will figure it all out and automatic deduct through my taxes refund?
