A 1040EZ covers that case and filing it is the cost of the stamp and envelope.
Intuit has blocked government attempts to do that by offering free taxes for half of Americans (that was the deal).
Of course they decided to renegade and only do 37% per their advertising.
Hilarious since they had the "federal is free but you need to pay for state" scam going already.
This is how pretty much every “free” tax program works.
Now maybe you miss out on some deductions if you just transfer a few numbers to the forms. But the standard deduction is going to cover most people until you get into big mortgages or charitable writeoffs.
