Bank statements and Tax return

[Yahweed]

hi all,

I am a bit confused and scared. I have an extension for Leave to remain application 2023 november. I made some capitals gain income which i told hmrc about and gave a tax return, for the year 21/22. The thing is, the money i earned (from forex) came through my friends crypto account first, and then through to my account as I did not have a crypto account at that time. I mention again that I have told hmrc and have paid the appropriate tax.

My question is, will Home office check the specific transaction and who that income came from? And if they do, will it cause a problem for me for them knowing that the capitals gain money came from a friends account? please keep in mind i have all the buying and selling transaction details, the money going into my friends crypto account, the money being sent to his bank account, and finally being transferred to mine, all recorded.

PS. I know that they only ask for 6/12month bank statements, and the income i recieved was in 2 April 2021, so it wont even be the most recent tax return that I am supposed to give. but i have read a lot of frightening stories about tax discrepencies and such and i do not want to make a mistake.

Help would be really appreciated!
