Need Help - Rejected Return

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.
