ISO and W2, turbo tax is penalizing me for under paying taxes

I exercised and sold ISO from my previous employer in 2024 on same day resulting in a taxable ordinary income. Now in 2025 I have received both W2 and I099B. In W2 only box 1, 14 and 16 were filled and net proceeds with cost basis is given through 1099B. After reading previous posts on this topic I have adjusted the cost basis to selling price while reporting this 1099B resulting in zero gain. But the problem is when I add this amount as wages as it is mentioned in separate W2 (from my previous employer), turbo tax is telling me that I have been penalized because I did not pay enough taxes since no taxes were withheld on this income in W2. This is an ISO exercise and sell event, and no taxes was withheld for this event and W2 is correct in that regards but turbo tax is calculating a penalty for this income. How shall I report this without triggering any penalty. Thank you for your time and your response will be much appreciated.
