Tax law changes

Just for closure sake, I finally received my RMD from Fidelity. They did NOT withhold any federal taxes at all (my discussion with them after filling out the W-4P form was that a "default" amount of 10% would be withheld).  And as I expected, NO state taxes were withheld either. I asked them to please deposit the RMD directly into my bank account as they have that information because of recent mailbox thefts. They MAILED it to me, and it took over 10 days to receive (each day checking the mailbox for fear of theft). Last week, I REMOVED my 401K from Fidelity and opened an IRA with another financial institution. I am so done with Fidelity. Today, I am making estimated tax payments to both state and federal to cover what Fidelity continues to call a "mishap." 

P.S. When I spoke to Fidelity on December 6, they said no taxes were withheld because I failed to indicate an amount in the ADDITIONAL TAXES line on the form. What??!!
