If you are in the section of TurboTax saying 'Tell us about the health-related accounts you had in 2020', you can check 'None of the above'.
A Medicare Advantage MSA is an Archer MSA designated by Medicare to be used solely to pay the qualified medical expenses of the account holder who is enrolled in Medicare. Contributions can be made only by Medicare. The contributions aren’t included in your income.
Since you have an HMO health plan, this does not apply to you.
