20 day PTDY for medical retirement

I’m so confused right now, hopefully someone can help! I’m trying to get the 20 day PTDY approved in conjunction with my terminal leave but my 1SG keeps pushing it back saying I need a form from my Peblo to have it approved. I contacted my Peblo and she has no idea what he’s talking about. Is there someone else I can go to? Or am I supposed to submit this leave with someone else?
 
It depends on service how the process works. My personnel folks automatically approved mine.
 
I haven’t spoken to the commander, they are never at the company every time I go in. Hopefully soon though, I’m trying to set it up where I can talk to them
 
I got medically retired and only got 10 days ptdy from my O-5. Will be starting terminal leave this Friday.
