Paying capital gains on crypto - more than one transaction, do I put them in one?

Hi, I am trying to pay capital gains on some crypto currency transactions. I made 'gains' via two transactions. I am trying to pay via the Capital Gains Tax real time transaction return but there doesn't seem to be space to report more than one transaction. Am I supposed to lump the transactions together, in which case, should I just put the date of the first one? There is also a space to upload documents but it is unclear what these documents should be. Is a spreadsheet detailing the two transactions sufficient? Thanks

Hi,

If both were in the same tax year, then yes, include them together and use the date of the first one. The documents will be details of how you worked out your gain, so if the transaction details confiirm the purchase and disposal prices, then that is fine.

Thank you.
