IRS might process your original return as filed.
Then they will catch up with your multiple 1040-Xs later.
This is not an issue for the Taxpayer Advocate.
OR
you have only one current return on file because 1040-X e-File submits your entire tax return again and 1040-X becomes your new tax return.
It is a 1040-X now so you will have delay in processing.
P.S. If IRS is confused by this, it is confusion of their own making.
