You are correct that under the Federal form using Form 5696 you can calculate a window credit. However this was talking about a Minnesota state form, the M1NC form. On M1NC, line 3 Section 129 in the instructions, Energy Efficiency Homes Credit, was NOT referencing this window credit. The Energy Efficiency Homes Credit was something else. Therefore, what was reported on form 5696 for windows does not have to be reported on M1NC, it is referencing something else according to the information received from the Minnesota Department of Revenue Individual Income Tax help line on February 6, 2020.
