After you file

Thanks got helping! I did this because I received a letter stating I was having an audit and to review my return and if anything was wrong to amend it. 
it said I was getting a refund of 3079 and then the next screen wanted me to set up payment for the 4k. I don’t owe 4k. That’s just the difference between the original and amended return. It’s acting as if I received the payment and owed them back 4k. 
What do you think I should do at this point.
