Detroit City Tax - Non Resident - Partial Year

Hello,

We are jointly filing our tax returns for 2020. Due to covid, we were working first 3 months and rest of the year we worked from home. I remember previous years TurboTax used to ask for a number of months worked in Detroit as a non-resident.  I don't see an option to enter just 3 months. please provide steps. 

Thank you!

Nat
