Sorry---TurboTax software for 2020 is no longer available. It is also too late to receive a refund for a 2020 tax return. But if you owe tax due for 2020, it is owed with late filing penalties and interest.
There may be other 2020 tax software available if you google it. But any 2020 refund has been forfeited.
