My client did not provide a 2nd W2 that was issued. Ignored my emails concerning lower W2 wages that last year and "anything missing"...signed e-file authorizations, and 1 hour after I e-filed the return mentions the 2nd W2 (this was last Thu so Superseded comes into play somehow or not???)

The original return filed shows $5500 refund. 1040X shows reduced refund of $1500. 

Not sure what to do regarding the $4000 payment generated by the 1040X. Should I wait until the original refund is issued then file the 1040X? Could be the IRS corrects and send correct refund.

OR file the 1040X without the payment? OR is there another suggestion...

Thanks in advance for the guidance.
