You can take a huge withholding from your IRA distribution, but if you only took 20% withholding it might not be enough to cover the taxes due, depending on your tax bracket.
So yes, it can be done– but did you do enough?
Consult a tax professional. You’re probably safe if this is the first time it you took your RMD. You can certainly avoid a penalty if you paid at least 90% of the tax shown on the return for the taxable year or 100% of the tax shown on the return for the prior year, whichever amount is less.
