My return was rejected with this error: - 601ERRV:2, CustHdr_17 - ?:? - Invalid SMS Number. Must be between 10 and 10 digits.
I have no idea what that means, but I didn't file last year so I am assuming that's why, but I don't know.
Does anyone know? (I am in South America (Colombia) and I can't call the 800-number).
Thanks in advance!
