Thanks - I ended up doing the second method. I already had a spreadsheet where I did all the calculations separately for both places, so I knew what the total work-space-in-the-home expenses should be. I added up all my expenses at both locations and entered them on t777s. Then, using the square foot area of the second place I lived, I calculated what the % area used for work would have to be to get the total work-space-in-the-home expenses.
I'll keep my spreadsheet for the CRA should they ask.
However, it seems strange that TurboTax doesn't let you fill in 2 t777s forms. That would make it much simpler and would describe the situation correctly.
