Need Help - Rejected Return

[Annoyed_]

Recently had to amend my tax return to account for a 1099-NEC that I received late (after I filed).  Not a huge deal.  I use TurboTax desktop and filed the amended return.  Everything went smooth and looked good.  No errors, so I e-filed the amended return.  About an hour later it came back rejected.  I got the following error message:

/Return/ReturnData/IRS1040X/NetChangeOrigRptOrPrevAdjGrp/TotalAdditionalDeductionsAmt - Data in the return is missing or invalid. Please double check your entries.

Went back into TurboTax but the review button did nothing.  I reviewed the tax return by hand and noticed nothing out of the ordinary (I'm not a tax professional though).

I looked online and scoured the internet and found 3 possible reasons.

1.  The IRS is not accepting amended returns right now for 2025 taxes.

2.  There's a processing error with the TurboTax software that might be fixed on 3/6/26

3.  My return is messed up and I need to find the discrepancy.

Just looking for a little clarification.  Any assistance would be greatly appreciated.  Thanks.

Does column A exactly match what was on the last accepted return? Some amend by changing the original return to see what it will look like or to get a head start on amending, rather than starting with the amended return link which results in rejection.  Another possibily is perhaps you filed the amended return too soon after the original. 

the rejection message does not come up on a websearch

Since you used TurboTax desktop to file your return, hopefully you saved a copy of the original return before you amended it.  If so, try making another copy of that original return and start the amended return again.  Then, wait until after March 6 to electronically file it.  

This should eliminate two of the possible causes - the possible TurboTax processing error and the unknown missing or invalid data problem.  If it is still rejected, filing by mail is an option as a last resort.
