At least for 2020 Turbo Tax Home & Business (may be other versions as well)
Step by Step Instructions are wrong for 2019 income!!
Software asks for line 10, QBI deduction, instead of line 11b, taxable income.
Line 10 in 2019 is the QBI deduction, which for most people in the US, will be zero.
Line 10 in 2018 was taxable income.
The user instructions for 2020 did not get updated with the new line number from 2019, it is still asking for the 2018 line number.
This could cause a lot of issues when Turbo Tax is calculating 2020 numbers based on zero income in 2019.
