Entering data directly in the forms mode is not supported and you must know exactally what you are doing. Many form entries come form other forms and worksheets. Form entry voids the TurboTax accuracy guarantee.
What actually goes on 4a depends on how you interrupt the convoluted line 4 IRS rules. It also depends if you have other 1099-R's or if and one was partly rolled over and part converted. The line 4a rules have many "if's" and exceptions.
You can read the line 4 rules here: pages 28-30.
