I am trying to amend my 2018 tax return because I received a corrected 1099 composite form after I filed and am using the PDF with all the worksheets that I printed when I filed initially as reference. When I look at the taxable income amount on the original 2018 return, the tax calculated by TurboTax is just under $3000 less than doing the calculation manually. My QDCGTW numbers are correct.
