HSA penalty for non-coverage

For TY2023 I had a high deductible family health plan with an HSA account.  At year end, my ins carrier advised my plan was being discontinued and I was being matched to new plan for TY2024, which I accepted assuming it was similar, and since I wanted uninterrupted coverage due to ongoing medical issues.  

On 4/18/2024 I made a max contribution ($9300, I'm over 55) and have paid $11,705 in medical expenses YTD.  As I am now actively looking to renew or replace that plan, I discovered that my existing health plan for TY2024 was not in fact a high deductible plan.  What do I do to rectify this?  Do I reimburse myself for the $9300 contribution?  Do I also reimburse my HSA account to cover the medical expenses I paid this year from my HSA account?
