Estimated tax amount
I had completed 2019 turbotax entry and got federal tax amount payment due $2,868 and 2020 estimated payment $1,896 X 4 = $7,584. I also asked my CPA to prepare my 2019 tax return and got federal tax due amount $2,866 and 2020 estimated payment $419 X 4 = $1,676. I am wondering why turbo tax shows this much $5,908 difference to 2020 estimated tax. Estimated tax 1040-ES amount turbotax showing is reliable?
