I live in NJ. My spouse was under my HDHP insurance plan along with his daughter until November. He has a new insurance from his job and he and his daughter was covered under that plan instead of my HDHP plan. Meanwhile, my employer has been deducting the HSA for both my spouse and myself for the full year. Do I need to repay for the 2 months that he's covered through his own family health insurance? What form do I use and how do I enter that in my W2 1040 tax return? Thank you.
