So long story short, I decided to do my taxes by myself as I’ve been doing for the past years, and I was really stupid this year, and literally forgot to add all my expenses. It came up that I owe +8000 dollars (obviously money I don’t have) so I double checked, realized my mistake and immediately filed an amendment, which came up to me actually getting 600 dollars back as return. They haven’t even receive the amendment, let alone processed it, but sent out a letter saying I have 4 days to pay the 8000 dollars. What should I do?
