Thank you Gabriel.
I followed the steps you mentioned, in step 4, I had the first option, however I still entered information in my spouse's file. I don't have other partners, only me and my husband each have 50% share. In step 8, in the page of "T776-Rental property identification", I don't see a field "Percentage interest in the partnership" but I did fill "Your share of ownership if other than 100%" as 50%.
When I look at my return's PDF file, on Statement of Real Estate Rentals, it shows my percentage of ownership is 50%, but under "Details of other co-owners and partners" section, no information showing at all, all blank. Everything else looks alright though.
On other pages (other than Statement of Real Estate Rentals), his information shows properly.
My husband and I always file separately, is it the reason? Please help! Thank you!
