I fail to see what being interested in the state of continued being of something has to do with having been the inventor.
IIRC you can't deduct relocation expenses, wardrobe for work, books and training materials, or a whole bunch of other stuff on a 1040 EZ.
So sure, as long as you want to overpay your taxes you can file in about 45 seconds.
For the rest, it is still up to me to declare additional incomes (e.g. rental properties) or deductions (e.g. donations). It does simplify though the process, especially for "W-2" employees.
Even a 1040 "long form" (2 pages) with itemized deductions for mortgage interest isn't that complicated.
I file about a 10 page return, 1040 with schedule A, schedule C, self-employment and various others and I always do it myself on paper.
If you are at the point where you think you need TurboTax, you're probably better off just hiring a local CPA firm to do your taxes.

Filing the state return electronically is different by state, but often either doable or you can mail it in.
