If you have a filter to circulate the water, the heater will keep the water at an even temp. (If you don't have a filter, there will be cold spots in the water.) I'd put the heater nearer to the filter outlet.
Your turtle is a hatchling/under a year and healthy? If so, a water temp of 77-78F would be good. If your turtle is older, have the water temp in the range of 73-75F.
