That is a big piece of it. Turbotax recalls my data from last year (where it is applicable) and posts it in the form in the right place.Honestly, the fact that H&R Block stores and inports all my stuff from last year is a huge reason I use them. ( I know many other online services do too) That alone is enough reason to keep me from trying to use the Federal and Alabama online solutions.
There is no reason I am aware of that the state of Alabama cannot do the same thing, though.
