Thank you! When I use Turbotax the putative Effective Tax Rate is indeed the Total Tax divided the AGI (not Taxable Income) Yet even the TurboTax info page (https://turbotax.intuit.com/tax-tips/irs-tax-return/what-are-tax-brackets/L8jeM6XaJ##) gives the incorrect information saying "Your effective tax rate is the percentage of your income that you owe in taxes. To find it, divide your total tax by your total income."
