<prompt> Human: I usually mail in my taxes but surprise! I just received my tax forms back in the mail. It did not get sent and was returned to me. I believe they made a mistake in reading the address I cross my 7s like shown in the zip-code. They used a marker and wrote over my 7 so the post office could not deliver it. Obviously, now is past the tax deadline but I still have the original letter with the postmark date. Should I re-send my taxes with the original envelope inside a new envelope? Would I get penalized for sending this because it is now late but I originally sent it on time? Has this happened to anyone else and what resulted out of it? I will try contacting my state department of revenue but unfortunately its the weekend. Here is what it looks like:If you look closely, you can still see my 7 underneath. I think my address looks clear but someone didnt think so. Im kind of angry about this. I owe the state some money but I dont want to get penalized for it being late.  <response>: Seems kind of silly that the PO couldnt figure out where to deliver it since Im sure thousands and thousands of returns were going to the same address that week, and there were probably entire truckloads of mail going to that one address.
