Federal Tax got rejected when I update my spouse new SSN from last year ITIN

[Srtech]

  This year my spouse got SSN and used it to file federal, but got rejected for wrong AGI. I tried may things but didn't work. Finally I put back her ITIN which was used last year , then federal got accepted. Do you see any issue here? How do I update my spouse SSN ?

The time between the Social Security administration changing the information until it is passed to the IRS and updated in their system can take a few months. if you are missing credits due to the ITIN, you can submit an amended return later with the correct information. 

I would recommend you e-file an amended return before October 15. E-filing will shorten the refund delay. Please:

• Save a copy of the original return before doing an amended return.
• See how to file an amended return.
• Follow your amend at track an amended return 
• See Can I e-file my amended state return?
