ITR form to show closure of CGAS

I had fixed the LTCG of 20L in CGAS a/c in March 2018.
Shown it in ITR2 as exemption u/s 54 of A.Y. 2018-19.
In Feb. 20, I purchased and possessed the property worth 20L basic value from my own fund and closed the CGAS a/c. later by getting approval on formG of Assessing ITO.

My total income for AY 2020-21 is below 2.50 L.

Now for A.Y.20-21, should I show the receipt of same?
If yes, in which ITR and in which schedule??
Immediate guidance will help me in filing ITR in time.
