Just pirate TurboTax. Torrent it, set up a fresh windows VM with Internet access via VPN, install/update turbotax, crack it to get the state version, make sure it's got live versions of all the forms you need, disconnect Internet access (never to be reconnected), copy previous year's data files to VM, do taxes, print out and file by mail, copy data files off to long term storage, save VM image in case you need to rev…
Or just use CashApp Tax. Your procedure makes it sound like Turbo Tax is the only game in town. Turbo Tax isn’t worth any of the effort you mentioned.
Just quickly looking at CashApp Tax, it appears it is an Android app that likely will want network access to function. If that meets your requirements, good for you. But it doesn't meet mine. I'd also rather use the same software year to year so that information is carried forward, rather than being subject to whichever way the startup winds blow.
