I have the exact same problem. This has gone on for several years. Have been filing the tax electronically, and manually producing the T1135 using CRA's fillable PDF form. I need to the the detailed method, and have 8 different equities to report in section 2 shares of non-resident corporations. Have purchased Ufile desktop, and was able to successfully do the form there. Starting this year, I will be reporting using Ufile, so I can file both the return and T1135 electronically. I will no longer be buying turbotax desktop.
