@kayak-headgear-meddle , Intuit is free to define "effective tax rate" in TurboTax any way that they want, no matter how meaningless the result might be, since there is no legal definition of this phrase in the tax code. As previously stated, Intuit has chosen to define it as Form 1040 line 22 divided by line 11.
No matter how it is calculated, it's still a pretty useless number other than for comparing your tax situation to someone else's.
