It indicates my Payer's TIN is wrong, it is not. It's the same number I used last year. What's up????

Make sure you are choosing the correct format of the ID number.  On some forms, you have to specify whether the federal ID number is in an EIN (XX-XXXXXXX) format or SSN (XXX-XX-XXXX) format.  It might be the format and not the actual number that is causing the problem.  See image below.
