Single 1099-R for normal distributions and Roth Conversion

I received a single 1099-R form showing my IRA distributions. However, 50% of the funds was normal distribution (cashed out) and the remaining 50% was used for a Roth conversion (both of which were taxable events). Currently, I entered 2 different entries into TurboTax representing the 2 amounts to book-keep the Roth conversion. Is this necessary, or should I just combine into the single amount listed on my 1099-R form (If I split, with the IRS be confused with 2 entries, but only 1 form)? Or do I need to request 2 different 1099-R forms with the appropriate balances?
