TurboTax has a limit of 30 T5008 slips. If you have more than 30 T5008 slips, you’ll need to add the amounts from each box together and enter them as one T5008 slip in TurboTax (ex. the sum of all box 20s on all your slips go into box 20 in TurboTax, the sum of all box 21s go into box 21 and so on).
