In 2022, my crypto-currency transactions was limited to one for perhaps $200 CAD

Whereas I'd like to document this transaction, the vendor whom I'd paid is non-responsive to my queries for more info... no longer using that email and all messages purged. Q: Forget it or in this year's tax return, submit an estimate for c-c activity? Or perhaps amend later if I get info later?

If the cryptocurrency transaction resulted in a capital gain or loss, you should report the transaction on schedule 3.  This does require you to have information on the purchase and disposition of the cryptocurrency.  Does your wallet not have details on the transactions?

@pirateinuk Yes, you can submit an adjustment at a later date if you receive more information. Please see our TurboTax FAQ for guidance: How to Change Your Tax Return After You’ve Filed
