I am filing my tax return and want to upload my slips (T4, T4RIF, T5008, ...) to my return so I do not have to manually enter the amounts. Does the software allow me to do that?

The software allows you to automatically download the slips you have on your CRA account to the tax return. Go to 'Transmission' on the menu bar and click on 'Autofill my return'. You will be prompted to log in to your CRA account on your browser and then come back to the software to select which forms you want to be filled out. If the slips you have at your possession are not available on the CRA, you can add the manually to the software by choosing the appropriate form from the list.
