How to report dividends earned by investments held in trust on my personal tax return?

We transferred some investment assets to a Keystone (grantor) trust last year. I understand that the interest/dividends from these investments should be reported on our personal tax return. What's the best way to do that within TurboTax? How do I identify that those dividends were earned by the trust investments vs. our personal investments, since the transfer occurred mid-year.
