Rectification request AY 20-21

I had filed ITR for AY 20-21 and got a demand notice. So, i filed rectification request with form 10E. But same was rejected and i had again received the outstanding demand. I had again applied for rectification and simultaneously paid outstanding demand too. 

Now, in March-2022, i have received rectified intimation where there is refund due. However, in the refund amount that amount which i had paid additionally (for outstanding demand) is not reflecting. How shall i raise request for that amount since ideally, if the return rectified then outstanding demand should be returned too. kindly advise.

Thanks
