Hi, thank you for using TurboTax Live Community
Eligible dividend gross up from actual dividends does not apply to corporations. Because of this corporations only record the actual amount of dividends, not eligible dividends. Usually a trust(T3) would only report eligible dividends to a payee who is either individuals or Trust.
Corporations are not able to claim a dividend tax credit either. This is mentioned on page 51 of the T3 guide:

Hope this helps
