Have never entered a T5008, can I enter them all this year?

[TurboTaxBrenda1 · Accepted solution]

You will not be able to enter all your T5008 this year on your 2018 income tax return. You can however, enter this years on your 2018 income tax return. 

For prior years you will need to do adjustments. You need to enter the slip on the tax year that is specified on the slip.
