Anyway to correct turbotax's mistake saying I had excess contribution to HSA? The total contribution $2000 was way below the limit. I called fidelity to confirm that.

There is no option provided to deny or correct the mistake Turbotax made on the wrong number of excess contributions for HSA it provided. I heard I wasn't the only one who called fidelity for the same issue with Turbotax. If by design, this is unacceptable to force user to opt in paid service.
