Your contribution limit depends on the kind of HSA coverage you have. If you have family coverage (that covers yourself and your spouse), then your limit is $8300 even though your spouse also has coverage from Medicare. (Your spouse can't contribute, but you still can.)
However, if you have single coverage, then your limit is $4350. Maybe you switched from family to single coverage when your spouse enrolled in Medicare and forgot to update the HSA bank on what kind of insurance you have.
