I found information on this site. Looks like I can allocate 0% to my son by following the procedures below. That would leave my return, which I already filed alone.
"I'm on my parents' health plan, but not on their tax return; I didn't get a 1095-A; and there are amounts in column C on my parents' form
In this case, TurboTax will ask you to enter a 1095-A. You'll enter the info from your parents' form. The next screen will ask you about your health plan being shared, so check the box.
Then you'll see a screen asking for shared policy info. You enter the following:
- Enter the Social Security number in box 5 (recipient's SSN) on your parents' 1095-A.
- Enter the starting month and ending month that you had the insurance.
Now you'll be asked to enter percentages for Your Premium, Second lowest cost Silver plan (SLCSP), and advanced payment.
You should see amounts on your parents’ 1095-A, columns A, B, and C. You and your parents should agree on what percentage of those amounts you’ll claim on your return, and what percentage they’ll claim on theirs. You can use anything from 0% to 100%, as long it all adds up to 100%.
Example: Darcy is working and isn't on their parents' tax return. They're on their Marketplace health plan and listed on their 1095-A. Darcy didn't receive a 1095-A in their name.
Darcy's parents have to figure out how much of column A (monthly enrollment premiums), column B (monthly SLCSP), and column C (advanced payments) on the 1095-A will go on their return and how much will go on Darcy's return. It was decided that Darcy will enter 10% of those amounts on their return, and Darcy's parents will enter 90% on their return. They could have decided to have 100% on the parents' return and 0% on Darcy's return."
