Safe Start can be used at any time, other than when medicating, or immediately after adding an ammonia reducing product, etc. You are lucky the animals are getting along. Eventually, the turtles will eat the fish and shrimp. Since this is essentially a turtle tank, you should be doing 50-75% water changes weekly to remove their waste, as they produce quite a lot. I would just recommend waiting about 24 hours after a water change, then adding the TSS. Once you add it, you need to wait at least a week before another water change.
Also, you will need to reduce the nitrite to 2.0 or less, as nitrite is not just toxic to the fish and shrimp, but to the bacteria as well. It will not bother the turtles, that I know of.... Unfortunately, nitrite is very difficult to reduce, you pretty much have to do water changes daily to keep it from climbing higher, and wait until the bacteria that your tank currently houses can bring it down some, then add the TSS.
