How are ETH gas fees handled?

How are these handled in the program?

My gas fees are substantial this year, and I want to deduct them from my taxes, or factor them into my cost basis. I have not seen anyone answer this question yet. Please help

When it comes to cryptocurrency, you pay taxes on capital gains. That includes not only selling it for a currency, but using it to make a purchase or even trading it for other cryptocurrencies. You factor in the total capital gains, which would deduct any associated costs, that being gas fees.

According to intuit.com:
“You can either increase your cost basis or reduce your proceeds to reflect these fees.”
