Missed to report Capital Gains in FY 24 - 25 (AY 25 - 26)

Hi All,

I missed to report my Capital Gains of around 34k and some FD interest in FY 24 - 25

I got to know that I can file ITR-U to fix this.

I downloaded the offline utility excel, but its too much complicated to fill.

Can I ignore this mistake or do I have any easier option?
