"HSA says my total contributions for 2025 is $8,288."
What happened is that you received a distribution of $328 as a return of the excess contribution and you deposited that $328 back into the HSA as a personal (not through your employer) 2025 contribution. That combined with the $7,960 contributed via your employer in 2025 makes your total contributions for 2025 be $8,288.
