How to Amend 2020 and 2021 returns?

[aroy0911]

I know I need to amend 2019, as I received amended K-1 for both years.  The amendments were due to depreciation basis for a real estate investment, that caused depreciation expense that was too low and a basis in the property that was incorrect.  This mistake in 2020 also affects my 2021 return.  Both were prepared and filed with Turbo Tax premier?  How do I go about amending  both 2020 and 2021 returns.  Will I have to redo the 2021 return from scratch importing information from corrected 2020 return?

No not from scratch.  To amend you need to start with the original filed return.  Then manually enter the changes from the prior year amended return.  So do them in order 2019-2020-2021.  You can't transfer (or import) from the prior year.
