To amend the 2020 Michigan return, you must initiate a federal amendment to return into the program and update Michigan.
To do this in TurboTax, follow these steps:
- From Tax Home, scroll down to Your tax returns & documents and Show More.
- Go to 2020 and select Amend(change) the return.
- This must be selected before any changes are made to the filed return so that Form 1040-X shows what was filed first, the change, and what is filed now.
- Once the Amend(change) return is started, follow the prompts.

As you note, TurboTax requires that I initiate a Federal amendment in order to do the Michigan amendment. The Fed IRS has asked that we not file amendments (except for certain circumstances that do not apply to me). I changed the E-File to "not ready to file" for the Federal amendment. A couple screens later, I can view the forms that will be E-Filed with Michigan. One of the attached forms is the U.S 1040-X.
On the one hand, since I am not actually filing a Federal amendment, it feels dishonest to me that the Michigan amendment would include that as an attachment. On the other hand, the Michigan Treasury website has encouraged tax payers to E-File using the original software used. This makes me think they are OK with what TurboTax is attaching to the amendment. I am hesitant because I obviously don't want to file false tax forms. What to do?
