I know what the issue is but appreciate all that attempted to help so where is the problem. The subnet we are using for AWS is 10.20.0.0/24 now I was checking the routing on my firewall and finally notice this

route INSIDE 10.0.0.0 255.0.0.0 10.16.169.10 1

so because the AWS subnet falls into the 10 subnet according to the route it throws it back to the switch interface and that is why I am seeing that Duplicate SYNC message when I see the logs. Once we changed the AWS IP address to outside the 10 subnet it worked. Again thank you Jesse P for your help much appreciated!!!! Let me know if you have any questions
