Incorrect SSN on an amended form

[SensibleandHourly]

Ugh, ugh, and double-ugh. Not sure if it was a typo or if the client misspoke, but the paper amended forms I sent yesterday had an incorrect ssn. I can't believe the client didn't catch it when I was pointing out various sections of the paper form for him to sign but there you have it, he didn't. First three digits should have been 377 but instead shows as 372. So, not sure, do I send an amendment for the amendment asap, or wait until it is rejected? Thank you!! 

p.s. Is tax season over yet? 😉

It probably won't be rejected, IRS will probably match it to the correct number and either process it or send a notice asking for confirmation.  If you managed to call, they would tell you to wait 45 days.

Thank you!  Sounds reasonable.
