You do not need to enter anything about your employer on the 1099-R screen. After you enter the form, you will be asked what you did with the money. If you rolled over any of the money and put it back into a qualified plan, you can indicate that then. If you kept the money, don't indicate that you rolled it over and TurboTax will get the income correctly reported on your return.
Amounts you rollover are not taxable. How does a retirement plan withdrawal (Form 1099-R) affect my taxes?
The link above has information about exceptions to the early withdraw penalty if applicable.
