How do I complete T2 Schedule 3 for T3 Dividends (Box 49) ?

I have dividends received from a Cdn Entity and I need help in completing Schedule 3 on a T2 form.

I am assuming that these are the entries on Schedule 3:

• Column A = Entity Name
• Dividends from a Foreign Source?  No
• Dividends subject to Part IV tax?  Yes
• Column F (Box 240) = Amount in Box 49 on T3
• Column G1 (Received After 2015) = Amount in Box 49 on T3
• Part IV tax before Deductions.  Dividends received after 2015 (Box 275) = Automatically calculated by TurboTax
• GRIP/LRIP: Column F deduction type:  Not sure what this is?
• GRIP / LRIP: Indicate Eligible Dividends: Do I enter the amount in Box 49 on T3?

Is this correct?  Is there a guide to completing this schedule?

Thanks for your help !
