If I have my health insurance under my father but file as independent how do I document my coverage?

If you were covered by a plan through his employer or other NON-marketplace policy, you will simply answer Yes, I had insurance all year and No, it was not one of these plans. There is no documentation required.  His employer would have sent a 1095-C to him which is kept for his records (you may want to get a copy of it for your records), but this is not entered anywhere on your tax return. 

If you were covered under a plan through Obamacare, you will need to answer Yes it was one of these and then enter information from the 1095-A.  You will then need to allocate the premiums based on how you and he agree to split them.  You will also need to look up your SLCSP and enter the percentage that applies to you.  You can find that by using this tool from Healthcare.gov. https://www.healthcare.gov/tax-tool/#/
