Demand raised for 'Self assessment tax' amount AY25-26

A user paid self-assessment tax of Rs. 11740 for AY25-26 and filed their return, but has received a demand notice for the same amount. The tax is reflected on the Income Tax portal and AIS, but the user cannot find an option to specify that the payment was made under the 'Self-Assessment Tax (300)' minor head. Suggestions include checking the demand status on the portal's worklist and denying the demand with payment details, or filing a revised Income Tax Return (ITR) before the deadline of 31st December 2025.
