Withdrawal Advice

What's the best way to take out 30K. I've lost 40K, won 30K, but can't file tax returns because it's via my parents. I don't want to take out checks for 2500 or bank wires for 5000 too often. I've opened a separate bank account for these transactions so as not to get my personal account frozen, but I'm also concerned about depositing foreign checks into a new bank. I deposited a 3K check some 10 years ago, and sure, one or two checks per year probably doesn't draw red flags. But do I keep it to just three or four checks for 2500? Or two bank wires for 5K? That sounds like structuring even if I deposit every other month.
