Where to enter capital gain in Business Incorporated My company has investment. T3 shows capital gain Box 21, also amount in Box 42 return of capital from Trust.

My holding company invests retained earnings in mutual fund.  I received T3 showing 3 amounts: 

1. Actual amount of eligible dividends in Box 40; 
2. Capital gains in Box 21, and 
3. Return of capital from the trust in box 42.  

1. I entered dividend in 8096 under Revenue.  Hope this is correct.  Will dividend tax credit calculated by Business Incorporated?  
2. Where to enter Capital gains?
3. Where to enter Return of capital?

Thanks!
