Taxation on crypto selling through Indian exchanges

I have been accumulating cryptos in coinswitch at various prices in small small quantities. But when i'll sell, it will be mostly in one go and TDS will also be deducted in one go. Now my query is, while i file ITR 2 for crypto, it'll ask transaction wise profit details. As of now what i was doing, i convert these entries in 4-5 times and show a lump sum amount. And also show buying price higher (bcoz selling can't be modified as TDS deducted on that) so that taxation reduces.

So my question is, is it a right method to file tax by converting let's say 100 entries (usually buy crypto of 1k-2k every time) into 4-5 entries. and then also modifying the buying price. Can IT Department ask me for further details?
