Http 500 server error, challan not generated on successful payment of income tax

[NikhilG]

@NikhilG As per the ORM team, if both of your payment got sucessful by now and you are able to download the challan, you need to do revised IT return, add both the CRN in Tax Paid section and claim refund. Thats the only way.

I think no need to revise return as the additional tax will show in 26as they will automatically refund it. Revising a return like this attracts scrutiny
