You might have more than 30 T5008 slips > there is a limit in TurboTax on how many T5008 slips you can import through AFR > 30 is the maximum.
You need to check the amount with the portfolio you got from your financial broker > if you have more than 30, you can add more in the Forms mode or you can combine them under one slip ( add al boxes 20 and add all boxes 21)
I hope this was helpful
