Category B/D pop up after the file is e verified

What to actually do — since the return is already e-verified:

1. Don't panic-refile yet. A pop-up defect warning at the time of e-verification is a system-generated caution, not automatically a Section 139(9) defective-return notice. Check the "Pending Actions" / "e-Proceedings" tab on the portal to see if an actual notice u/s 139(9) has been issued citing this defect — often it isn't, and the return processes fine despite the pop-up.
2. Cross-verify both Form 10-IEA acknowledgements via e-File → Income Tax Forms → View Filed Forms — confirm the AY 26-27 form shows "Valid" status, and the AY 25-26 form isn't showing as "invalidated."
3. If a 139(9) notice does land: respond within the given window (typically 15 days, extendable on request) by correcting the AY-linkage field in Schedule Part A-General — by then the software glitch may be patched, allowing the correct AY to be selected. This response is filed against the notice, not as a fresh revised return.
4. If no notice is issued within a reasonable time and processing intimation u/s 143(1) comes through clean, no further action is needed — the pop-up was a soft validation warning that didn't escalate.
