[Question] Is crypto only taxable if you withdraw? or if you convert?

edit: USA

I tried to time the market a month ago, had a stop order limit for a certain amount of BTC, it sold everything, which I knew it was going to do but didn't even consider taxes cause I thought you get taxed if you withdraw.

I just checked my tax form on the crypto exchange and it says I have $X,XX.XX amount of gains.

Its listed on the exchange as

Outgoing FROM 0.XXXX BTC —> Unknown Estimated Tax Impact $X,XX.XX

When I report this during my taxes will I get taxed for the sell? – Even though I don't think I made profit?
