Tax help

So I made like $300 in alt profits last year. Nothing crazy. They problem is I did it all on coinbase wallet and every time I export it to a crypto tracker, it's wrong. All of them are way underreporting my profits. In fact, the only app that seems to have it right is the regular coinbase app which gave me an estimate of what they think happened in the wallet, and it's about $300 of profit.

Now, should I just report $300 even though I don't have the exact amount, and all the crypto trackers are saying something way lower (they're all saying anything from $50 to - $50).

Does it even matter with this low of a profit?

I just don't want the IRS yelling at me.
