If/When to update Marketplace if income comes from an investment?

I’m a full time student in a state without Medicaid expansion. School doesn’t offer health insurance, but I work enough at a part-time job to qualify for tax credits for marketplace health insurance. I signed up due to a SEP & used my work income of $1,400/month, but I’m not sure if/when I am supposed to include income from a stock? (I cannot afford health insurance without significant tax credits, so I am scared to mess this up.)

Every year before taxes, I get a tax form from my grandma’s financial planner that lists dividend income from some stocks she has for me. (I don’t actually get paid because her planner had always re-invested it, but I use include that tax form info when I filed my taxes for the job I had before school.)

Every year the amount is very different (last year it was $2,000 in dividends but also a lot more than that in losses). I don’t know the amount until the tax form comes from the planner. (My grandma only trusts her planner & won’t give me access to the specific stock info, but that’s a separate issue).

Can I wait until Feb/March 2023 to update the marketplace with my annual dividend amount, or are they just wanting my total job salary pre-taxes? (I’m considered a 1099 contract employee, so I also pay quarterly self-employment taxes to federal and state).

Thank you!
