The 2 digit year code may be for a different reason than for Battle Creek. Please double check the form listed. 

Running through an example of a Battle Creek, MI tax interview in TurboTax Online, I did not see an area asking for a two digit code. The only area asking for dates required a date range for when the income was earned. The format was MM/DD/YYYY. For January 1, 2020, the entry would be 01/01/2020.

For more details and to see the Battle Creek BC-1040, check page 9 of the 2020 Battle Creek 1040 Booklet.

When I go to e-file my Michigan state taxes, I'm getting a notification that I need to fix my return. It is taking me to a W-2 Worksheet for the Battle Creek taxes, and under the "Allocation Test Worksheet" section, Question 4, it is asking me for the dates I worked remote at my home. I've filled it in with a 4 digit year code, but it is saying (and displaying on the worksheet) a 2 digit year code. Below is a screenshot of where this is occuring for me.

That did the trick. Thank you @KathrynG3 - very much appreciate the help!

Excellent-Glad to hear it. You're welcome!
