2019 software is not going to work now. TurboTax no longer supports 2019, nor do they provide updates for it. You are too late to receive a refund for tax year 2019---any refund has already been forfeited and the IRS will keep it. But if you owe tax due for 2019, you will also be subject to late filing penalties and interest owed.
You might need to seek help from a local paid tax professional to help with 2019. Or......use the paper forms and prepare them by hand to mail in.
