I did call the number and in the end, the answer is that TurboTax doesn't split the CCA automatically between co-owners based on ownership percentages and we need to calculate it manually on the side and enter it manually for each co-owners.
I don't think this is intuitive since nothing is mentioned anywhere that TurboTax needs you to do it this way and is likely prone to have users assume it did the split on all and submit erroneous information.
In one single flow, you are asked to enter the co-ownership information (with the percentages), the revenue, the expenses and the CCA, then at the end TurboTax automatically splits the Revenue and Expenses as per the co-ownership percentages but not the CCA.
How should the user know that TurboTax will not apply the split to the CCA but it will for the revenue and expenses?
Your competitor has a drop-down with the option to tell the tool if you want the CCA deduction to be applied only to your profile or equally against the co-owners as per the percentages.
You should seriously consider adding this option to your solution.
Using the software to complete my income tax but having to calculate myself on the side the amounts and the splits seem counterproductive and defeat the reason for using the software.
