Then, when I go back to the home page of Turbo tax, under "Wages and Income", at the section "Retirement Plans and Social Security", I see $120,000 next to "IRA, 401k, Pension Plan... Withdrawals".
My question is: Shouldn't I see there $100,000 instead of $120,000?
$120,000 is correct. The amount reported here is intended to show the gross amount taken out. What you did with the distributions has nothing to do with what is in this total. This total is only to give an indication that you entered all of the Forms 1099-R that you intended.
Your Form 1040 lines 4a and 4b are also correct, including the ROLLOVER notation.
