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
