So this game only actually prepares taxes for people with extremely simple tax returns (no retirees, no Uber drivers, no interest/dividend income, no sales of capital assets), and only if they live in states which don't need to file tax returns. Bold dream, but I feel like you're not living up to it.
Actual tax advice: Ignore the big corporations and look for a local tax preparer. I'm biased since I am one of those, but you should be able to get better service and lower rates when you're personally working with someone who doesn't need to support lobbyists and national marketing campaigns.
