Hard forked tokens are not taxed at the time of receipt. Instead, the full sales value in DKK is taxed when the forked tokens are sold. You can read more about this here [link to tax rules/hard forks].
Do you have a deposit in your transaction list that is rightfully the receipt of hard forked tokens?
If you mark it as a hard fork, the correct tax calculation will be applied to it (as described above).
You mark a deposit as a hard fork by:
1. Clicking on the “label” icon to the right in the transaction line.
