Obviously, I just want to enter estimated tax payment once, not twice, however, when I preview the forms it is shown in 1040 as well as in schedule 3, not sure why, hence I asked this question. Looks like I have to call Turbo Tax to understand this, might be it could be a worksheet, not sure.
In 2019 schedule 3 form I see there is a line to enter estimated tax payments, but in 2020 schedule 3 form there is no such line.
