After you file

I got cp63 letter saying i had to file 2015 taxes. I did. And mailed them in last week. They should receive them today... but i just saw where i mailed them to the wrong address. So I’m sure it’s going to screw everything up. I’m so mad at myself... trying to do everything in a hurry. I’m on hold now trying to see what to do. It will probably take forever to see my refund!
