I was covered under a HDHP in 2024, but switched to the EPO for 2025. A contribution I made on the last day of the year posted for 2025. HSA won't change it.

What will happen when I file my taxes for 2025 or what should I do at this point. I'm retired so my former employer isn't involved in the deductions etc. The contribution was made on the last day of the year, but they posted it for 2025.
