How to file a 1099-R on trustee-to-trustee transfer

Hello experts,

My work retirement plan made trustee-to-trustee transfer funds to my Roth IRA for contribution portion and T-IRA for the gain portion, involving no payment or distribution to me. I received one 1099-R with code G for the contribution portion and the forms 5498 reflecting both are rollovers. 

But TurboTax accounted my gain portion as the taxable income which is already rolled into the T-IRA. How this can be corrected in the tax filing or how do I handle the situation? 

Thanks. Kent
