HSA Excess Contribution: How to withdraw the full individual limit and report it in TurboTax?
Hello everyone,
I realized I made an ineligible HSA contribution for the 2025 tax year and need guidance on correcting it before the filing deadline.
My Situation:
1/1/2025 – 12/31/2025: I had a Marketplace Silver Plan ($0 deductible, non-HDHP).
9/1/2025 – 12/31/2025: I also had an Employer-sponsored HDHP.
The Issue: Because I had the Silver plan for the entire year, I think I was ineligible to contribute to an HSA at all. Is that right? However, I contributed the full $4,300 individual limit. 😔
My Questions:
Removal Process (Optum Financial): I have the Optum "Excess Contribution and Deposit Correction Request" form. Do I simply list the full $4,300 for 2025? Does Optum calculate the "Net Income Attributable" (earnings/interest) automatically, or do I need to calculate that myself from my statements before submitting?

TurboTax Reporting: How do I reflect this removal in TurboTax?
Do I need to complete Form 8889?
Where do I enter the "Excess" so TurboTax knows the money was pulled out before the deadline?
Since this $4,300 was pre-tax, I assume I now need to report it as "Income" somehow, so it's taxed—how to report this?
Thank you for the step-by-step help!
