Its a new form that goes along behind the new postcard sized (its actually 2 half pages) Form 1040.
Various different things are reported on it, it resembles the old style 1040.

I think in my case it is triggered by Student Loan interest payments and their tax break associated it with them. Was this reported differently last year? Because now i have to upgrade to be able to file and is no longer free =(
Yes, the new forms did not exist last year. The IRS scrapped the old 1040EZ and 12040A and replaced them with a new "simple" one page 1040 for everyone and 6 new schedules. The Free Edition only supports the simple one page 1040. Any additional schedules require Deluxe or higher and student loan interest requires schedule 1.
