I contributed to my hsa in 2018 when I was ineligible to have an HSA account. I spent entire account on medical and closed it in 2018. How do I report this on my taxes?

I contibuted $150.00 in 2018 but realized my mistake in March and cancelled further contributions. I spent the entire $700 in my hsa account by June 2018 on medical expenses and closed the account at a zero balance. I messed up. I am unclear how to report this on my taxes.
