sorry. the other day I was able to do what was posted and on the asset screen select M or N. i did not save the test return. today when I went back and tried both step mode and forms mode I could not repeat the results of the other day. NO M or N. the only thing i could suggest is use the code for nonresidential property.
however, I left the code blank and depreciation was computed correctly. you can't efile 2020. on final review the fact there was no code for the property did not pop up as an error though in forms mode the worksheet says not done. don't know if leaving the code blank will cause and error when rolling to 2021
