I have a 25 yr old son that is filing separate tax return. We have Marketplace insurance, What do I use for the percentages for the insurance

You get to choose the percentage. Please see the screen shot below.

 Child/Children on another tax return

If you share a policy with someone who is claimed on another tax return (usually a child), you can take the number of people on your tax return who are covered on that plan and divide it by the total number of people on the plan. This would be your percentage of premiums, SLCSP and advanced payment of the premium tax credit, unless you agreed on a different number beforehand.
