**Describe the problem:**  
I transfer 2163,47 USD to coinbase  
I pay $2,163.47 USDC with my coinbase debit card  
The “cost basis” for this transaction was $1,163.22.  
So the “gain” was $1,000.25  
That’s wrong because USDC is a stablecoin. There is no “gain” ,  
How can I adjust the cost basis ??  
**Which exchange/wallet is this regarding?**  
coinbase

**How did you import data into this wallet?**  
API

**What have you tried to fix this so far?**  
I created a manual transaction and soft deleted the old one but still the gan keep in 1000.25
