My employer sent me an amended w-2c due to a mistake in reporting the HSA company match. Do I need to file unamended return?

The amount that is deficient does not put the HSA above the allowed amount.

The error you described is on the employer's side of the W-2 (HSA company match); as long as it did not put the HSA total over the allowable limit, you don't need to amend your return to report it.

The IRS will get a copy of the W-2C and update your tax file accordingly - you do not need to report the change on an amended return.
