Resync from beginning.

Unclear what else to do.
I did use Coinbase Pro (which is also imported).
Im wondering if there is a issue between those two.

I have exactly the same issue.
What I found after comparing my actual Coinbase transaction history with the import to Koinly, is that when I have in previous years sold crypto from Coinbase, the USD went straight into my bank account in every case. Koinly, on the other hand, assumes that the USD stays in Coinbase on every sell. They need to fix this or at least let us manually mark the transactions that when sold, went straight into our bank account. I believe this is because until recently, Coinbase didn’t even allow users to hold USD in their account, so it was straight from bank account into crypto, or straight from crypto into the bank account. As a result, it thinks I have a bunch of USD in my Coinbase account that isn’t there, and never was.
