How many days from my ETS date can I start turning in TA50?

Not sure how it works nowadays, but I've always been to the mindset that as soon as you have your ETS orders, you go get your Clearing packet from S-1 then you just start clearing.

SPC Dominque Lee you can get a letter from your Command to turn in early if they authorize it. Go to supply see if they have any examples.

When I was in supply it was generally the month before you were ETSing, but that was the Guards.
