Ok this may be a DUMB question but I am confused I have a Form 1040-V Payment Voucher....well that stub has a mailing address in Dallas, Tx but my mom did our taxes and she ask the man to write the mailing address on the envelope and he put Austin, Tx
Can anyone tell me the correct place?? I need to get this in the mail tonight obviously.

I always wait until the last min. to do things LOL
