How to show SGB interest in iTR

If you can add one more raw it would be advisable, otherwise add it to sav bank interest.

Thank you , does it mean if i add 1 more row for SGB and show it as Rs.5000/- then the SB interest should be changed to 25000/- ( as i need to deduct the SGB interest from it)?

Yes, SB interest would be separate in case SGB interest can be declared independently.
