When you get to the Finish & File section in TurboTax Online it will give you the option to download a preview of your return that includes all the forms before you file.

When I try to print a copy of my tax return for mail in, why don't the ONT428 got printed. I found there are some boxes in the T1-KFS has 5 boxes of it. Is that enough for the CRA?

When you print to file your return, you will have the one page with a barcode, which is what the CRA uses to get the other forms you filed. When you printed your condensed return, you should have approximately 8 pages. 

Thank you for choosing TurboTax.
