Disclaimer. I do not work for Intuit. I just finished another kid's return, and it asked me to answer a question. So here we go.
I'd say this. If you do not have a mortgage, then it made no sense for you to even start with TT Deluxe. While it " Searches 350+ tax deductions and credits" and can "Turn donations into big deductions", unless you give a TON of money charity, the only deduction that is likely to get you over the Standard Deduction is mortgage interest.
If you do have a mortgage, then TT Deluxe did it's job and determined that after all of the deductions you could take, the Standard Deduction was still better for you. And it seems fair that Intuit wants to get paid for that.
And this all assumes you used the online version. If you bought TT Deluxe download, like I did, it was worth it because it comes with the State filing - AND - I got to do 5 returns (oh joy).
