A rollover is not a regular contribution to an IRA. Do not enter a rollover under Deduction & Credits, enter it only by entering the From 1099-R and indicating what you did with the money. The amount distributed form the 401(k) will be included in box 4c of Form 1040 but the amount rolled over will be excluded from the amount on line 4d. The word ROLLOVER will appear next to the line.
