USA Tax preparation

Spring is here: blue skies, very nice temperatures. Every day.
In the USA I did do my tax filing every year with Tax preparation software that I bought, through Amazon, from HR Block: "TaxCut", an online download. Mid April is the deadline for filing.
This year was the first time I used a free online version of Intuit:"Turbo Tax". Available if your income is below a certain minimum.
It worked very well. 2 days ago I spend 45 minutes filing in questions and uploading the end result. The next day I got an email that both my Federal Tax and Arizona state tax filings were accepted!
