I made a partial withdraw from a regular IRA. I then moved all of that money into a roth which allowed in kind transfers. I then paid for the withholding using other funds. I sent the withholding as a quarterly tax and was penalized for not paying quarterly tax on it for the whole year. The withdraw and the check sent to the IRS was in the same quarter within a couple days. How do I avoid this in the future so I am not penalized?
