When using TurboTax Standard Online, click on Find in the top right-hand corner and type foreign income, select it and click Go. You are able to NETFILE the T1135 form. Once you NETFILE your income tax return, it will give you the option to NETFILE your T1135 as it is filed separately from your income tax return.
Therefore, you may need to open your return and go to the "File" Section and click on the T1135 NetFile. This is a step you may have forgotten
