When claiming my parents as dependents who have obamacare, what can I do to reduce my tax liability b/c the amount is increased since it includes as my health insurance?

I have health insur. from work for my family & me. I claim my parents as dependents & they have Obamacare. When filling out their 1095-A my tax liability goes up, when I do not fill it out it stays within usual range. It goes up b/c it's including my insur. info. What should I do to reduce tax liability to a normal range?
