ITR3 Tax paid and reflecting in Form 26AS - yet shows 0 on the portal

A user has filed their ITR-3 and paid tax online, which is correctly reflected in their Form 26AS. However, the filed return still shows the tax paid as zero on the portal. Other users suggest filing a revised return to include the challan details or submitting a disagree response to any demand notice if the return is processed. It's noted that while tax payment reflects quickly in Form 26AS, the IT portal's update can take a few days.
