Thought I'd share my Turn Automation settings for planting, I got them dialed in so it works quite well this year on two headland passes.
I have a DB44 planter (44' wide). Probably need to adjust turning radius accordingly and the minimum turn angle.

I really wish the Turn Size had a different band. I'm curious if anyone uses a smaller number than 7. That seems works well for me, but 6 is really tight, 8 is too wide, but ok if I happen to make three headland passes.

Turn Size   7
Start Turn  +3'
Max Turn Speed   5 mph
Minimum Turn Radius   20.5' (start at planter width/2 - 1.5. It worked pretty good at 21', but I tightened it up a bit and it goes around nice at 2.5')
Maximum Turn Angle   85° (This should be dialed in on your particular planter/tractor)
Turn Deceleration Threshold 39" (I don't really understand this setting, but that's what it is at)
Response Aggressiveness  3
