But why is it this feature is not available for previous tax years now? Why do I need to wait until Netfile opens in order to gain access to the data I need from previous years taxes?
In the meantime, since the CRA only gives me 30 days to respond from the day they sent their letter, I downloaded a copy of their worksheet and filled it our manually to match what TurboTax would have provided.
Worksheets are not available in the Online software. You will need to download and print them from the CRA link and fill in your information to send it to the Canada Revenue Agency (CRA). If they are asking for your T3 or T5 information slips, you need to send them a copy of your slips as seen in the images below.
Why is there no ability to print out a T5 or T3 Slip summary for your own records (i.e. the T5 or T3 data (boxes) that you entered off slips received)? The data has been entered in the Turbotax software, you can see it online, so why can't you print a one page summary of the slips entered with corresponding boxes? Would it be possible for Turbo tax programmers to offer this option for future years?
