Do I understand correctly:  If, say, a $4,000 RMD was distributed with $1,000 withheld for Federal Income Tax and $3,000 going to the recipient, and the recipient re-deposited the full $4,000, then I should check the box for Line B1 "Entire distribution rolled over" in the section Rollovers, Roth Conversions, etc.?  Doing that does not reduce the amount owed on the return from the result when just the 1099-R distribution had been entered.  This was from a Beneficiary IRA with 1099-R Distribution Code 4 (Death) marked.  Does that make a difference?

Thank you for any help you can give.
