Step by Step is in TurboTax desktop. In TurboTax desktop, you have option of input. Either step by step or forms option. You will see this in the upper right hand corner of the screen. If you are using TurboTax Desktop, at the select return to open screen you will see the amend return option. If you are using TurboTax Online, you will not see a Step by Step option.
To amend your return in TurboTax Online, go to your Tax Home then scroll down to "Your tax returns and documents" then select "Show". Select the year in question then the amend return in the right column. Follow the steps to amend a previous year's return. Currently the 2020 amend return function is not ready in TurboTax.
