For my 2020 taxes, I have only entered two W-2s in TurboTax desktop software and another popular tax prep online system. If the federal tax tables determine tax liabilities on taxable income, why are the tax due amounts not the same between two software systems? TurboTax is calculating a tax due difference of $68 more than the other system. To me, this is a significant amount of difference. Enough that I may consider switching to the other tax prep system. I plan to enter my deductions in both systems to see how the two play out!
