Hi Lulukern123, I hope your day is going well.
You can add the fees or commissions paid for original purchase of your coins to the cost of your coins. But, you cannot add fees for transfers from one wallet to another to cost basis.
The info below if from a turbo tax article
When calculating your gain or loss, you start first by determining your cost basis on the property. Generally, this is the price you paid, which you adjust (increase) by any fees or commissions you paid to engage in the transaction. This final cost is called your adjusted cost basis.
