Self assessment tax not ceredited in intimation u/s 143(1)

Dear Experts,

I got an intimation u/s 143(1) from CPC Income tax department.  They have raised a demand of Rs. 750/-.

But I find that they have not given tax credit of Self Assessment Tax paid by me.  What should be done ? Can I get it corrected in nay manner ? How to bring this to the notice of CPC ?

Yes, the tax deposited is showing in the AS 26.
