I filed the 2023 tax year separate but hen amended the return with joint which AGI do I but in the box?

Please click on this TurboTax article for more information. 

 

Check these items as well to ensure you have the correct number.  If you: 

• Filed late last year after mid-November or your return was processed after that time—try entering 0. 
• Amended your return last year—make sure you’re using the AGI from your original return, not the amended one. (If you only have a 1040X form, it’s on line 1, column A). 
• Rounded your AGI to the nearest dollar—be sure to round up when it’s 50 cents or more and down when it’s 49 cents or less. 
• Filed with your spouse last year—you and your spouse have the same 2023 AGI. (Don’t split the AGI amount or enter  0  for one of you). 

 

Time-saving Tip: If what you entered is correct and you continue to get a reject, you won't be able to e-file. There's probably a data mismatch at the government, or some other situation beyond your control that prevents your return from being e-filed. In this case, your only option would be to print and mail in your return. 

 

This article will give you instruction on how to print and mail your return. 

Yeah, you might need to try a couple ways.

 

Normally, the AGI you use must be the same as for what You & Spouse originally filed, before being Amended.  At least that's what is required for people who file regularly , and only amend for other reasons than completely changing from MFS to MFJ

Thus, if your original MFS tax returns were actually "Accepted", then you would use the line 11 AGI on each separate MFS 1040 tax return, separate number for each of your respective 2023 AGIs

But yeah, not sure what happens if you amend to MFJ...might depend on when you amended....
