Retirement tax questions

I am in a similar situation where I had my 401K after-tax contributions go to a Roth IRA, and the earnings on those contributions go to a traditional IRA.  When you say to split the Form 1099-R, do you mean to manually input two manually created 1099-Rs to reflect two transactions, and not include a 1099-R in the form it was provided to me?  Will this spike an audit flag to the IRS since something doesn't match?  What about TurboTax accuracy guarantee when I start to play around with the forms?
