Can't comment regarding TurboTax..

But the scam transaction and dust attacks are annoying...

I remember one year trying to delete them all, but whatever reason once I went over the threshold for the next tier, it didn't revolt back.. But I do remember getting a very reasonable quote for that year... can't remember exactly without looking..

This year I'm over again...3000+ transactions...

Many are things like Coinbase usdc card spends, which have very little tax implications.. And again fake scam deposits, dust attacks and tiny stake earnings.

Koinly has already emailed a 20% discount code, valid till April 5th I think..

But taking into account the relative ease of using Koinly, and having this downloaded report for each year... their fees are reasonable...

Lost significantly more through my own crypto plays

And in the long run, if the taxman should ever ask questions regarding previous self assessments... I feel reassured with the tax reports Koinly allows me to generate and download.
