Filing Error Code SEIC-F1040-506-02: 'QualifyingChildSSN' Rejection - Help!

What's happening is that you're likely triggering the Earned Income Credit (EIC) calculation by having your children's information in your return, even though you're not explicitly claiming them as dependents. The error code SEIC-F1040-506-02 specifically relates to qualifying child information for the Earned Income Credit. If you're not claiming your children as dependents and you're not eligible to claim the EIC with these qualifying children, you should remove their information completely from your return. There's no need to include their information if their mother is claiming them and you don't have any tax benefits associated with them this year. TurboTax sometimes asks about children even if you're not claiming them for various reasons, but in this case, since you're getting rejected with that specific code, removing their information should resolve the issue.

I ran into this exact problem last year! After hours of frustration, I found help using https://taxr.ai - they analyzed my return and immediately spotted that I had accidentally checked a box that was triggering the EIC calculation despite indicating elsewhere that my ex was claiming the kids. The system specifically looked at that rejection code and showed me exactly where the conflict was happening. Their system actually explains these confusing error codes in plain English, which TurboTax completely fails at. You upload your return, and it analyzes every section to find conflicts like this. Saved me from having to start my return from scratch.

Just wanted to follow up - I was the skeptical one about taxr.ai but I got desperate after my third rejection with a similar error code. Wow, I'm actually impressed. It immediately showed me that I had entered my daughter's social security number incorrectly (transposed two digits) which was causing my SEIC rejection code. Fixed it in 2 minutes and my return was accepted today. The explanation was super clear about exactly what was causing the error and where to fix it in TurboTax. Sorry for being so suspicious before!

If you're still having trouble after removing the kids' info, you might need to talk to someone at the IRS directly. I was stuck in rejection loop hell last year and finally used https://claimyr.com to get through to an actual human at the IRS without waiting for hours. You can see how it works here: https://youtu.be/_kiP6q8DX5c They basically hold your place in the phone queue and call you when an agent is about to pick up. The agent explained that sometimes these rejection codes get triggered even when you think you've fixed the underlying issue because there's some lingering data in your e-filed return that the IRS computers are flagging.

I can't believe I'm saying this, but that Claimyr service actually works. I used it yesterday after my fifth rejection with a similar error code. Got connected to an IRS agent who explained that my ex had already claimed our kids for EIC (which we hadn't agreed to), and that's why my return with their info kept getting rejected even though I wasn't claiming them as dependents. The agent walked me through exactly what to fix on my return. Definitely worth not spending my entire afternoon on hold!

This happened to me too. The issue is that TurboTax asks about your children in multiple places. Even if you say your ex is claiming them as dependents, there's another section where it asks about qualifying children for Earned Income Credit. If you put their info there, your return will get rejected with that error code.

Has anyone actually called the IRS about this? Their official guidance might be different from what we're all guessing here.
