There is a transaction when I generate my tax report that is showing capital gains. I suspect that transaction is a transfer of BTC from my exchange to a wallett. Transfers from exchanges to walletts of BTC do not incur cap gains.
1 - how do I verify my assumption is correct?
2 - if i am correct how do I edit the transaction so that it does not incur cap gains on the report
Did you pay a fee on the transaction in BTC? That would trigger a gains calculation.
If both exchange wallet and the receiving wallet are added to Koinly, then it will be treated like a Transfer. Does it show as a transfer in Koinly? Post screenshots if you can!
