I received a 1099-DIV form in April, after i filed my 1040A and received my refund. The amount was incorrect, so to avoid interest penalties, i sent in a payment for the taxes owed using the current 1099-DIV form by April 15th. An IRS rep told me that the payment would be applied to my account until they received the 1040X. I have not filed a 1040X yet b/c i have not received a corrected form, and i thought i had at least a year to do anyway. The IRS just sent me a check for my payment plus interest. 1) I'm confused - does this mean i don't owe additional taxes - i thought they would have seen the 1099-DIV form, which was not included in my 1040A? 2) If not, how do i avoid further penalties since they sent my payment back? Thank you.
