The 1040 lines 4c and 4d come from the 1099-R and your answers to the interview questions.
4c is the distribution amount and 4d is the taxable amount if the distribution amount and 4d is the taxable amount are different. If all of the distribution amount is taxable then it will only be on 4d. Therefore if more than one 1099-R it is entirely possible for 4d to be more than 4c.
