Need help for taxes, kucoin say its synced but 0 transactions

Describe the problem:
I put in my kucoin api waited like an hour and it said synced but say 0 transactions. I
have the most transaction on this exchange

Which exchange/wallet is this regarding?
kucoin

How did you import data into this wallet?
api

What have you tried to fix this so far?
resyncing it a few times

I’ve went through this too. I found that this account would always freeze. I have about 50k total transactions on that account. Also, when adding new wallets with the API, leave some time for each before uploading another source so that it has time to automerge. I have found that when I upload back to back, the auto merging does not occur, but uploading slower to emptier accounts tend to combine orderrs quickly. I would suggest for that exchange that you use CSV
