Where 2020 TurboTax asks how much you spent on various types of medical expenses, make sure that you include the medical expenses that were paid with funds from the HSA in 2020 (even if that HSA distribution was to reimburse you for medical expenses incurred in a previous year). TurboTax automatically subtracts from the medical-expense total the amount that you report in the HSA section has having been used to pay medical expenses and includes on Schedule 1 only the portion of entered medical expenses in excess of your HSA distributions in 2020.
