If my income was below $25,000 (this is what I also reported to Healthcare} why is my refund reduced when I enter form 1095-A?

When you applied for the Marketplace insurance, you made an estimate of how much you would make in tax year 2023.  

You received a discount on your insurance that reflected that estimated income.

If you earned more than your estimated amount, you will have to repay a portion of that discount.

"If your actual allowable credit on your return is less than your advance credit payments, the difference, subject to certain repayment caps, will be subtracted from your refund or added to your balance due for years other than 2020. If your actual allowable credit is more than your advance credit payments, the difference will be added to your refund or subtracted from your balance due."
