<prompt> Human: Our Tax Advisor calculated my share of PTC and entered this while filing taxes. I now owe upwards of 4000 to the IRS. I am not sure if this is correct I do not think if my parents removed me from their insurance they would have paid extra 4000 in insurance last year. What can I do about this and has anyone else faced this issue before? Thanks in advance for the help.  <response>: What do you mean by they signed you up for Obamacare? Do you mean they left you as a named insured person on a family plan that your parents bought from one of the state exchanges, which was secondary to the insurance you had through work?Who was receiving the bills from the Obamacare insurance company and paying the premiums? If it was your parents any repayment to the government for subsidies should be their responsibility.
