The only way to open a .tax2021 data file is with the TurboTax software for 2021. If you don't have it, you can still buy it at this link. As an alternative you could try TaxPrinter. You send them your .tax file and they send you back a PDF of the tax return. Before you do this, ask them if the PDF will include the depreciation schedule.
TaxPrinter has no connection with TurboTax. I have never used TaxPrinter, so I cannot make a recommendation. I'm just making you aware of it.
